Radeon AIW 8500 DV

[Mr Bonhomme]

XFree 4.3.0 and xfree-drm are working for me with Xv (mplayer,xine) and dri (quake3), but one trouble:

-X freeze when switching several time between different resolutions (CTRL.ALT.+ several times, or for example use of xawtv fullscreen (switch from 1600x1200 to 768x576, then return to 1600x1200).

-when I launch X without loading dri, this problem doesnt occur.

-when I launch X with dri and without any windows (just typing X on command line in init 1) this problem does not occur. If i add an xterm (export DISPLAY=:0.0 && xterm) the trouble occurs.

I notice this from XFree.0.log, but I dont know what is it:
.....
(II) RADEON(0): initializing int10
(EE) RADEON(0): Cannot map SYS BIOS
.....

I try in depth 24 and 16.

Do you experiment better results ?
