Hi,

2.6.33 is working fine for my amd64 Debian testing system with a dual-screen
setup (Radeon HD3450 with VGA and DVI outputs). I compiled this kernel with the
new KMS radeon driver and with the appropriate firmware.

However, if I compile 2.6.33.1 and 2.6.33.2 (with oldconfig from 2.6.33), the
VGA output of my videocard displays everything much too bright, right from the
start of the booting process and also after starting the X server.
The DVI output works fine.

I'm sorry that I can't give more information, I'd be glad to test things out if
you tell me what to try. I searched the internet over and over again, but no
one seems to have the same problem.

Best
Benjamin Scherrer
