dri no more working with xorg modular

[Sascha Heid]

Hi All!

I had dri and glx working fine with xorg-6.8.2 on my Thinkpad X21
which has a ATI Rage Mobility Videocard.
Im running Gentoo-Linux and emerged/compiled Xorg Modular with DRI
Support (using the dri use-flag).

When starting Xorg, the DRI-Module loads fine, but later the driver
says that he is disabling dri:

I believe the card has 4MB of Ram and im running it at 1024x768 with
16bit Color.
Because of the last two errors i started another Xorg with 800x600 and
then i get:

(II) ATI(0): [drm] SAREA 2200+1208: 3408

Im using Kernel 2.6.16 with some gentoo patches.
When i run glxgears its working for about 2 seconds and then shows a
static image.


Any advice would be most welcome :-)
