Hi Paul,
thanks for your fast answer.

Sounds easy :)
But now I have another small problem...
Before doing any changes to the dri sources I did a make world on the
freshly checked out sources. After copying mga_dri to the right place
and restarting X I always get a seg fault after:
(II) MGA(0): [drm] bpp: 16 depth: 16
(II) MGA(0): [drm] Sarea 2200+664: 2864
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)
drmOpenDevice: minor is 0
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is 6, (OK)

I'm using the XFree 4.2 Debian packages for Brandon. A test with
mga-20020622-linux.i386.tar.bz2 from http://dri.sourceforge.net/ had the
same result as with the XServer from extras.tgz.
So I've to do some printf into os-support/linux/drm/xf86drm.c to find
that problem first (or is that a known issure?).
Bye, Michael
