This sounds rather nice. ;)
So you didn't use the standard Debian kernel (kernel.org + Debian patches)
at all. I already thought about that but hesitated to take the time
compiling my own kernel without knowing whether that helps. Too good that
you tried. I think sooner or later I would have tried it too, but its
good to know that this approach works.

An ACPI related issue or are there other problems with this driver?

Okay, that's fair. So it would stop an ISDN connection with my AVM
Fritzcard before suspending, which would be a good idea anyway. Only
thing would be that USB 2.0 PCMCIA card (which works marvellous under
Linux BTW). I would have to unmount things plugged into it, before
suspending.

Can you give me a hint where I can find that mailinglist? Is it an
official thing from IBM?

Sure! Thanks a lot Michael. I didn't think about the 2.6.9 kernel, since
the Debian packaged one didn't work at all on my ThinkPad.
Seems that the Debian patches have negative impact on running kernels on
IBM ThinkPad with full functionality. I really should have tried
compiling my own kernel! When I get around taking the time I will write
bug reports on that.
I will also try with Debian kernel package for 2.6.10 which should be out
now. Maybe it works better.

I did so shortly after I bought that used IBM ThinkPad T23 laptop. It was
fairly recent (well what you can call recent for T23) anyway. I upgraded
from 1.15 to 1AET61WW (1.17).
