I'm not sure if this is related, but here it goes:

Unllike you, I'm running a (single) ATI card in a laptop and have just
compiled and installed the 3.1.6-gentoo kernel.

Like you, when I tried to hibernate the screen but dark, but it never
actually completes the hibernation.  Similarly with suspend to RAM I
cannot recover from it and I have to power cycle it.

I have not had such a problem with this laptop since I bought it two
years ago.  All I'm thinking of blaming is the new 3.1.6 kernel.
