【求助】PXA27x开发板上用PCMCIA卡的问题！

各位好，有个问题折腾我半个月了，请大家来帮帮忙！

我想在Intel(R) PXA27x 的开发板上用PCMCIA的无线网卡，
首先我的PXA27x开发板上的arm-linux运行得很好，
然后我严格按照PXA27x的readme文档中的PCMCIA部分操作（该部分文档见下），编译了内核及pcmcia-cs 。
结果pcmcia-cs运行不起来，运行cardmgr时报错：“no pcmcia driver in /proc/devices“ ，
插入16位PCMCIA卡和32位CardBus卡都不亮灯。
后来我查了pcmcia-cs中的HowTo文档，它说是“Base PCMCIA kernel modules do not load“ 。
这是为什么？
编译arm-linux内核时，加入了PCMCIA/CardBus驱动，但这个驱动是为 PXA250/PXA210 写的。  
难道是因为PXA250/PXA210的驱动不支持PXA27x开发板？
不知大家是否遇到过相似问题？
恳请不吝赐教！！！



下面是文档PXA27x_readme.txt中的PCMCIA部分：

SCSI support  --->
I2O device support  --->

5.  In the ATA/ATAPI/MFM/RLL support page, select ATA/ATAPI/MFM/RLL support and
    then select IDE, ATA and ATAPI Block devices:

<*> ATA/ATAPI/MFM/RLL support
===> IDE, ATA and ATAPI Block devices --->

6.  In the IDE, ATA... page, select PCMCIA IDE support as a built-in:

[ ]     Auto-Geometry Resizing support
===> <*>   PCMCIA IDE support
< >   Include IDE/ATAPI CDROM support

7.  For the Xircom(R) Creditcard Mobile Adapter (CEM33), return to the top level and
    select Network device support:

Networking options  --->
===> Network device support  --->
Amateur Radio support  --->   

8.  In the Network device support page, select Network device support and
    select PCMCIA network device support:

• Network device support
  ...
  Wan interfaces  --->
  ===> PCMCIA network device support  --->  
  
  9.  In the PCMCIA network device support page, select the items with an * as built-ins:
  
  
  
• PCMCIA network device support
  < >   3Com 3c589 PCMCIA support
  < >   3Com 3c574 PCMCIA support
  < >   Fujitsu FMV-J18x PCMCIA support
  < >   NE2000 compatible PCMCIA support
  < >   Asix AX88190 PCMCIA support
  < >   New Media PCMCIA support
  < >   SMC 91Cxx PCMCIA support
  <*>   Xircom(R) Creditcard Mobile Adapter (CEM33) 16-bit PCMCIA support
  [ ]   PCMCIA Wireless LAN     
  
  12.2) Using PCMCIA
  
  To use PCMCIA, download the utilities from [url="http://pcmcia-cs.sourceforge.net"]http://pcmcia-cs.sourceforge.net[/url]
  using the following command:
  
  - pcmcia-cs-3.2.8.tar.gz
  
  12.2.1) Unpacking the Tarball
  
  To unpack the tarball, type the following commands:
  
  % tar xvf pcmcia-cs-3.2.8.tar.gz
  % cd pcmcia-3.2.8
  
  12.2.2) Modifying the config.in in pcmcia-cs-3.2.8
  
  To Modify the config.in, type the following commands:
  
  % vi config.in
  % cat config.in
    LINUX=/usr/src/linux
    PREFIX=
    MODDIR=
    UCC=arm-linux-gcc
    KCC=arm-linux-gcc
    LD=arm-linux-ld
    ...
  
  12.2.3) Building the PCMCIA Tools
  
  To build the PCMCIA tools in the Linux kernel tree, type the following commands:
  
  % make mainstone_config
  % make menuconfig  <= configure the kernel as above
  % make oldconfig
  
  To build the PCMCIA tools in pcmcia-cs-3.2.8, type the following commands:
  
  % make config

  The default responses for each question are adequate for most users.
  
  Consult the Linux PCMCIA HOWTO document for additional information about each option.
  
  Linux kernel source directory [/usr/src/linux]: /path/to/kernel
  ...
  Build 'trusting' versions of card utilities (y/n) [n]: y
  Include 32-bit (CardBus) card support (y/n) [y]: n
  Include PnP BIOS resource checking (y/n) [n]: n
  Module install directory [/lib/modules/2.4.21-rmk1-pxa1-intc2]:
  ...
  The Forms library is not available.
  
  Configuration successful.
  ....
  % cd cardmgr
  % make
  
  NOTE: cardmgr and cardctl are built-ins in the directory.
     
  12.2.4) Run on target
  
  To run on target, follow these steps:
  
  1.  Include the following commands into root file-system:

  % cp cardmgr/cardctl rootfs/sbin
  % cp cardmgr/cardmgr rootfs/sbin
  % cp etc rootfs/etc/pcmcia -R
  
  2.  Run cardmgr to monitor the PCMCIA slots by typing the following command:
  
  % cardmgr
  
  3.  Run cardctl to show PCMCIA information by typing the following command:
