I am not sure about the current state of things. AFAIK the problem was
with dri suspend support for radeon, and at the time at least, the card
was reset on VT switch to enable suspend. IIRC the patch was
incorporated into main the main tree quite some time ago.

I have no experience with S3 suspend (my laptop doesn't seem to support
it) but it does suspend with swsusp2 if I switch VT.
