valkyriefb as console

Hello,

a while ago I wrote a driver for the onboard video circuitry found in  
the Performa 6360 ( in OF it shows up as /valkyrie ) - supposedly it  
isn't properly supported by OF but as it turns out it is. Kind of.
Just setting output-device to /valkyrie gives me a funny looking but  
working console, but for some reason any attempt on loading ofwboot  
fails with 'CLAIM failed'. With output-device set to /bandit/ 
3Dfx,Voodoo3 it boots just fine. The bits & pieces needed to run the  
system console on valkyriefb should be in place, if I just could get  
it to load anything ( genfb can't work since OF still doesn't give us  
a framebuffer address and it would need glue code to attach to  
mainbus ).
So, any ides what could cause this and how to get around it? Sure,  
valkyrie is unaccelerated but as a simple console it's doing alright  
and people might want to use the PCI slot for something else, like  
fast ethernet or a USB2 card.

have fun
Michael
