I definitely had that problem. Don't remember if it was limited to my
t14amd or not. But I recall moving to a mainline vanilla kernel which
reduced problem. But be careful with those as I went through a patch of
problems with those as well more recently. I am nolonger using that
laptop so I can't tell you whether by now its fixed 100% but I believe
vanilla mainline did reduce frequency of the problems occurence.

sure your bios suspend behavior is set to linux if you have it. Hope you
have current bios as well.

Have you tried using Ctrl+Alt+F2 to get to a text console and logging
in there? If that works, try this to see if your display manager is
working:
ps aux | grep gdm | grep -v grep
If you're not using Gnome, substitute whatever dm you're using. I'll
leave the reason for the second grep as an exercise for the reader.
