Yeah, fairly normal. Use 'vbetool post', or other hacks to restore the
PCI config space. Jbarnes is working on 'real' suspend/resume support
that will live in the DRM driver. It saves and restores these registers,
along with the rest of the video register set. When that's ready, we'll
finally have reliable, BIOS-free S3 on intel chips.
