Does a simple "modprobe thinkpad" work?  The error message looks somehow
suspicious.  Can attach the relevant part of modules.conf (or just
/etc/modutils/thinkpad)?

No alsa works fine, but you have to use the cs4236 (IIRC) driver.

Doesn't make sense.  The implementations are broken.

But it makes sense to use apm.  You are lucky, since lately we had a
longish thread here on suspend/resume on ThinkPad 600es with kernel 2.6:

http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2004-January/014932.html

Specifically I created a patch that reenables suspend/resume for me (on
a TP600e 2145-4A0).  Please try to test it and report your success (with
details about your model) to me!  Since I can't recover the patch from
the archive I attach it again to this mail.


hth,
