Hi,Yann Desplanches  
  Yes,my cf card can work on at91rm9200dk just said like you.but I wait for a long \
time (about 10-20m). need wait all interrupts output info finished ,driver can work \
and mount is ok. So I changed source of driver ,make it fast (just 2s)
but I don't know, what' problem with the driver.
at91rm9200 not support  ide mode only support  memory mode.
the driver work for ide mode,it need interrupt,but at91rm9200 hardware design only \
for memory mode , it can't support interrupt,so driver always output info "lost \
interrupt". I don't know that is right? who can solve this problem.
I just delete printf in driver and I have the other question, can this driver support \
CFIO?,my cf wlan card can work ? The CF same to PCMCIA on at91rm9200? PCMCIA wlan \
driver can work for CF wlan card?

Hi!
(sorry for my poor english...)

Be carefull, you have a mix between cardmgr output (and "his" kernel
output) and mount output...

Perhaps my experience with compactflash on a at91rm9200dk can help you.
Without adjusting timeout (to be more fast in "polling mode"), I have :

    [root@cdfpap4 /]$cardmgr -v
    at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 33
    at91_pcmcia_configure_socket(): conf-> reset=0
    at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 33
    at91_pcmcia_configure_socket(): conf-> reset=1
    at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 33
    at91_pcmcia_configure_socket(): conf-> reset=0
    [root@cdfpap4 /]$at91_pcmcia_configure_socket(): config socket 0 vcc
33 vpp 0
    at91_pcmcia_configure_socket(): conf-> reset=0
    at91_pcmcia_configure_socket(): config socket 0 vcc 33 vpp 0
    at91_pcmcia_configure_socket(): conf-> reset=0
    hda: SunDisk SDCFB-64, CFA DISK drive
    ide0 at 0xc2a80000-0xc2a80007,0xc2a8000e on irq 3

And _after_ 30 seconds :

    hda: lost interrupt
    hda: lost interrupt
    hda: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error
    }
    hda: task_no_data_intr: error=0x04 { DriveStatusError }
    hda: 125440 sectors (64 MB) w/1KiB Cache, CHS=490/8/32
     /dev/ide/host0/bus0/target0/lun0:< 3> hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    hda: lost interrupt
    ide_cs: hda: Vcc = 3.3, Vpp = 0.0
    hda: lost interrupt
    hda: lost interrupt

Here i can mount (mount -t vfat /dev/ide/host0/bus0/target0/lun0/part1
/mnt/cf/ ). It's ok.

But if i mount during the 30s beetween the 2 outputs, i have the same
mount error of you :
     ...
     hda : bad access: block=0, count=1
     end_request: I/O error, dev 03:00 (hda), sector 0
     FAT: unable to read boot sector
     ...
