Just a note about 2.6.10-rc2/3 kernels: I also had some Problems with them. snd-Intel8x0 needs an update concerning PCI config save/restore and ehci-hcd causes problems after resume. uhci-hcd suspend/resume works for me, except that I must not plug or unplug usb devices while the system is supended. > Besides that, I think we could convince the X.Org developers that > the "get display working" bug is their problem ;-) > It seems they have merged some suspend/resume bugfixes for Radeon and > will merge at least one more bugfix in the next few days.

The various framebuffer drivers should know how to wake up the card. There were some discussions on the linux-fbdev-devel list about writing a lightwhight(20-30k) 8086 emulator for the kernel to avoid real mode hacks. As far as I know, this should be based on the 8086 emulator XFree/X.org uses.
