It is known problem. At least known to me. After reboot and typing 'reset'
type 'dmesg' and then look for 'Console: switching to colour frame buffer 
device...'. Above that message you'll find couple of radeon messages - 
and you have to remove all printed during register_framebuffer() from
driver source - it looks to me like that '#if 1'-ed code in radeon_write_code
is suspect.

You must not do any output during register framebuffer. If you'll output
one line, I believe that it will still work, but if you'll do more, 
kernel output is catched in upper Tux window instead of in the bottom half 
of screen. And if you'll print really much of info during 
register_framebuffer, kernel will die...
