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.
