Interesting  I installed Xubuntu on my TP600 just to check
if it would find my cardbus, and the result was opposite to
your experience  With acpi=force (default) the kernel
decided to disable CardBus-support

, but when I edited the grub-line and removed acpi=force,
the kernel got as far as it did in my original post; that
is, it notify when CardBus-cards are inserted or removed,
but I can't get 'modprobe prism54' to work (it loads the
module, but nothing exciting happens)  What distro did you
use, and is the wireless card 16bit or CardBus?  I can get a
16-bit PCMCIA-card going (kernel finds it automatically) but
am stumped when it comes to the CardBus-card
