squeeze/amd64/gnome - edid error, 5 minutes to boot

[Pablo Sánchez <pablos@adinet.com.uy>]

Hi there, new to the list.

I'm trying to run squeeze/amd64/gnome on a compaq 6820S .

Video card is a mobile radeon 1350 :
01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Mobility Radeon X1350]

Driver in use in "radeon", and it seems is using kms

root@nb-pablo:/home/pablo# lsmod | grep radeon
radeon                573612  2
ttm                    40002  1 radeon
drm_kms_helper         20065  1 radeon
drm                   142375  4 radeon,ttm,drm_kms_helper
i2c_algo_bit            4225  1 radeon
i2c_core               15712  4 radeon,drm_kms_helper,drm,i2c_algo_bit

The thing takes ages (like 5 minutes) to load and all around dmesg are :

which correctly states it has a resolution of 1440x900 .
It worked fine with lenny/amd64 on the same machine, also con ubuntu 9.10/amd64 .

I tried using xserver-xorg-video-radeonhd and works almost fine (no monitor detected but
behaves properly) , but no 3d accel .

So, i'd like to get it working with xserver-xorg-video-radeon , nicely.

That is, i'm requesting some help ...

Regards.
