Hi, I've got some questions:

Does VT switching work before suspending? You may still need to
specify the UseBIOS off option for it to work.

Also, are you suspending to disk or ram? Does it restore the video
state properly if you suspend on the terminal, with no X server
started? Are you using a frontend like the hibernate script for
suspending? Is it trying to restore the video state with something
like vbetool? (If not, you might want to give it a try)
