Following this; ejecting and reinserting the card again kills the kernel *hard*. (No Caps-lock or SysRq response).

I'm seeing the same basic problem on my IBM Thinkpad T40 running 2.6.15-27-686 #1 SMP PREEMPT Sat Sep 16 02:13:27 UTC 2006 i686 GNU/Linux.

If the IDE device (CF card) is inserted at boot, the device works ok. If ejected and reinserted, this Oops occurs:

pccard: card ejected from slot 0

This is a known problem. It's fixed in edgy by using the pata_pcmcia module. It likely wont get fixed in dapper.
