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.

No, I think it's the kernels problem. 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.

Cheers,
Stefan
