Hello,

I found a quick hack that seems to fix the problem (on my Packard Bell DOT M/A,
AMD Athlon 64 L110, ATI Radeon X1270 (rs690m)).

It's very simple and works for the kernel 2.6.34 and 2.6.35-rc2 :

* Open drivers/gpu/drm/radeon/rs690.c
* Find the line that contains "bool sideport = false;", line 236 for 2.6.34
* Change "false" to "true"
* Recompile you kernel, on simply the radeon module : make
drivers/gpu/drm/radeon/radeon.ko
* Install
* Enjoy

Now I have a question : why not using "radeon_atombios_sideport_present(rdev)",
or even "rdev->mc.igp_sideport_enabled" if already available ?

Cheers.
