[Linux-fbdev-users] Support for Radeon Mobility 9000 in 2.6

[Michael G. <mi...@it...>]

Hi,

I have been running 2.4.2* with radeonfb on my Radeon Mobility 9000 on
an Acer TravelMate 800LCi without a problem.
But after switching to 2.6 the framebuffer no longer works.

	* The driver in vanilla 2.6 gives me distorted output.
	* The driver from Ben's tree (penguinppc rsync) gives me distorted
          output too.
	* James latest fbdev.diff gives no output at all. (Only the backlight
          stays on)

Here is part of the syslog after inserting the module (patched with
fbdev.diff).

modprobe radeonfb:

modprobe fbcon:
The screen blanks afterwards, but the machine still runs.

Can someone tell me if radeonfb in 2.6 should work with my card right
now, or if this is a known problem?

Thanks in advance,
