Try building radeonfb in the kernel and booting with
radeonfb.default_dynclk=-1, let me know if that works. fbdev's in
modules have always been sort-of dodgy....

The "dynclk" thing has issues, the upstream code from ATI has some bugs
plus there is something weird going on which I suspect might be a
miscompile of a bit of code in there. I'll send a patch working around
that today.

Ok, did that. Same result. The only thing displayed is the system
caret. I can see it moving left and right while the system boots and
"displays" the messages (X is working nicely).

I did compile debug support, so I'm including the output.

Well... looks like radeonfb is actually working ... You can try booting
with radeonfb.noaccel=1 on your kernel command line and tell me what's
up ? I looks like your fbcon is having trouble actually. Not sure what's
up, I haven't had any report of that so far.

Ben.
