I'm also a T61p owner, and for me suspend is working. I'm using Linux
2.6.24 (32 bit version) and the newest driver from NVidia (yes, I know I
should be using the opensource driver, but it didn't work when I got my
laptop).

I haven't got hibernation working yet, but I haven't yet tried without
the NVidia module loaded (and as suspend works, hibernation isn't that
important for me).

Sound also works for me. Config at http://hogthrob.42.dk/config-t61p.txt

This is actually fixed by upgrading to the newest version of the BIOS.
I'm currently running version 7LETA7WW (2.07), and haven't seen the
problem since I upgraded.
