I'm just wondering why the clearing of video memory was added to 
radeonfb_pci_register?  The memory still belongs to vgacon at this 
point.  There are a few other problems with this:  there is a noticable 
delay while the screen is totaly blank,  vgacon can't save the text 
screen to the shadow buffer, and all further output until the takeover 
is invisible (vga font is wiped) so an oops here wouldn't be readable.
I added that to fix reports of users complaining they had garbage displayed
on boot. I didn't think about the interaction with vgacon (see, I have
absolutely no legacy hardware doing crappy VGA mode ;)

Maybe that should be reversed ....
