I need to get around to fixing that problem. I'm glad the general patch
that went in fixed alot of problems :-) It's a matter of the framebuffer
driver restoring its state when switching back to the console. Most
drivers have a problem with that. The current approach is to use the
xxfb_blank function to fix this up.

This is normal behavior. In 2.4.X you have the same behavior. Only vgacon
doesn't do this because it doesn't handle the differences in screen size
on VC switching.
