It is impossible to make video work after a resume from RAM (S3 resume) on all herdware configurations at the kernel level. However, there is a userland tool for that called s2ram (see http://en.opensuse.org/S2ram). Please try to use it.

Needs a s2ram patch to add me to the whitelist (will send in right now), works great with my Dell Insipiron 640m, thanks!

Time to update. The original description is not valid any more. It is possible to handle suspend/resume of the graphics from the kernel if a KMS driver is used. For KMS drivers, please report resume problems to their developers. If you have hardware there's no KMS driver for, you may try s2ram, but this is not guaranteed to work. Closing.
