In the previous 0-0-3 branch we almost never messed with the DRM, so it
was binary compatible between all snapshots. Now is exactly the opposite.
Nevertheless you shouldn't need to stop X if you're running your distro X.
You need only if you are running X from a mach64 branch, because in this
situation the kernel module is being used and the install.sh script will
surely fail to remove it from memory.

Please check that the mach64.o in the kernel, the mach64_dri.so and the
ati_{drv,misc}.o files in your system were indeed updated by install.sh
script. (They path should popup if you run "locate" with their name).
The reason is that I've changed the dripkg/install scripts sometime, and I
didn't receive any feedback (positive or negative) so something could be
going wrong and it's best to be sure of that before looking for other
explanations - especially since no one who built directly from CVS
experienced that so far.

Putting the check will take a little more than that (I have a paper
submission deadline in 1 June and I'm barely starting to do the research I
proposed to do in that paper, so I'm a great deal of pressure to get
results ASAP), but I can put the DMA by default so that the interested
ones can try. In the worst case, they can always use the
mach64-0-0-3-branch.
PS: Don't remove the working mach64-0-0-3 snapshot that you may have, as
they will eventually get deleted from the DRI website.
