Version 188.8.131.52 of the unofficial Parhelia driver available ("supports" Xorg 6.9.0)
Today I upgraded to Xorg 6.9.0 and hacked the installer script of the mtxdriver to
install on 6.9.0 too. Until now, I didn't experience any problems, system is up
and running now for about two hours.
Please keep in mind, that this is only a workaround and that I don't give any
guarantee, that it will work on your system neither can I be made responsible
for any damage that may be caused to your system.
* Added support for Xorg 6.9.0 in install.sh
* There is a warning during the compilation of the mtx driver claiming
that KBUILD_BASENAME is being redefined. I don't actually know, how to
get rid of this warning - so if you have an idea, please let me know.
The whole build concept definetly needs reorganisation, but I don't speak
Makefile syntax very well
