[Nouveau] nouveau kms causing hibernation problems

I have an old machine with working hibernation (pm-hibernate). I replaced the
graphics card with an NV05 one and now it fails to hibernate when using
modesetting. nouveau.modeset=0 works fine.
What happens is that very early in the process the display looses signal, and
the expected disk activity never happens (no led flashing). Then the machine
just hangs. I suspect that the progress information shown on the VGA console
in modeset=0 has issues with the framebuffer, and it crashes there.
On the other hand, googling for this gives me nothing, so I guess others have
this working fine.
Any ideas how to debug this?
