ati radeon M6 LY dri needs driver reload to work

[MB]

ATI MOBILITY M6 LY (found in many laptops, here a sony vaio) is a radeon 7000 serie, but is incorrectly reported as radeon 9000.

DRI does not work on first launch. It needs the drm and radeon modules to be removed (rmmod) and reloaded to work.

This thread describes the problem in details and provides a script to fix it (an init script that starts before gdm is launched. It removes and reloads the modules):

This happens to me as well!

Doesn't appear to work for me on an HP OmniBook XE 4500

I reloaded the modules, but nothing improved...

I suppose I should have said I'm using edgy...

Is it working if you try out a live cd with feisty fawn herd 5?

Yes, it works on my Omnibook xe4500
