True. I do it on my Dell 600m (Radeon 9000M) using usermodehelper and
it works just fine. It works both with VGA and X. I need to split up
the thaw_processes into two stages though. It may not work with fb as
fb driver resumes earlier. I use the patch below for the kernel and a
userlevel x86 emulator.

I have to say though, it will help if we have a such an 

emulator in the kernel.

Just a quick question: is this the right way to distinguish kernel
threads? I've been checking if the process has an mm context 
(if p->mm).

I guess p->mm is a better way to catch all kernel threads. My check
above actually catches all daemons (even userspace daemons like acpid).
