Well, it isn't actually blank, to be more specific, starting from
yaboot I get (copied by hand, may be incorrect ):
Please wait, loading kernel
** Then the screen clears and at the top I have **
... ok
opening display /[EMAIL PROTECTED]/ATY,[EMAIL PROTECTED]/ATY,Bee_B...ok

returning 0x0140000 from prom_init
Then no more text, the messages stay at the top of the screen. The
background is white, the text it black. The screen does flash once to
black and then back to white fairly soon after the message above
appears. Then I wait several seconds for X to start with the above 5
lines still at the top of the screen.
X starts up normally (the display goes black with the backlight on,
then I get X).
If I switch to console from X I get a distorted image of what I had under X.
Features are are roughly doubled in size (xterm taking up 1/4 of the screen
under X now under console takes up most of the screen) It is as if the video
device under console is interpreting the same memory as under X (Linux never
gave it something new to draw?), but parameters have been changed so the image
is distorted.
Here is some dmesg spew from the new radeon driver:
