Ok, I tried it (with 2.5.73), with slightly better success. I still
get oopses, but the system doesn't hang completely anymore. But the pcmcia
system (and probably more) is unstable afterwards. There are oopses
when shutting down as well...

Module ide_cs cannot be unloaded due to unsafe usage in include/linux/module.h:479
ide-cs: hdc: Vcc = 3.3, Vpp = 0.0
(this also happens without your patch. I reported it earlier for 2.5.72, but
I said that it didn't happen after I rebooted. With 2.5.73 (without your
patch) it happens every time.
The device still works though, even with this not very encouraging message.
Console messages when physically removing the card (I haven't mounted
it or done anything with it since inserting the card):

There are some weird messages about devices.
This is what it looks like when the card is in:
brw------- 1 eivindt root 22, 1 Jan 1 1970 /dev/ide/host1/bus0/target0/lun0/part1
This is what it looks like when it's been removed:
drwxr-xr-x 1 root root 0 Jan 1 1970 /dev/ide/host1/bus0/target0/
There is not /dev/ide/host1 when the card has not been inserted at all.
Hope this helps, Eivind
