That will definitely not be necessary when all is said and done. A
major driving factor of getting the modesetting done in the kernel was
so it would stand a better chance to handle suspend and resume. A
definite goal in all that is that banging the BIOS will not be
necessary and the card can be reprogrammed directly.

I read that the Intel kernel modesetting driver is lacking
suspend/resume support right now.

That being said, nobody except Fedora users even have the kernel
modesetting drivers yet. The disabling of quirks in smart-video was
supposed to be taking advantage of fixes in the DRM i915 driver that
went in to 2.6.26.

I'm pretty sure the current DRM driver is supposed to be handling
suspend/resume correctly and any issues should be considered a bug.
Whether you want to file those or just continue to work around them by
using vbetool, I don't know. See this bug, for instance.
