radeon framebuffer console all dark

[Riccardo Mottola <riccardo.mottola%libero.it@localhost>]

Hi,

my HP laptop with Turion CPU ad Radeon video is resisting efforts of 
getting BSD-ized! Unacceptable!
First issue is that the auixp driver hangs the kernel boot - working 
on that with Christos and Martin, but no progress.
Disabled that driver, next issue: once the framebuffer of radeon kicks 
in I get an all dark screen
Only a bright square cursor shows, moving as the kernel messages 
scroll up to the login.

Better checking (but I can't show it in a screenshot) I notice it is 
more like super-dark-grey on black: the text is unreadable, but it is 
there.
Blindly typing login and starting X11 gets a working and correctly 
display X, so it is the console.

Any suggestions? It is not a regression bug from 9.0: it is already 
bugged. I am just testing current kernel and noticed the issue 
continues.

Any ideas?
