Hi again.

I just found this thread: http://lists.freebsd.org/pipermail/freebsd-current/2004-January/thread.html#19836

Someone posted a kernel module which (hopefully) gives control over the display.

Unfortunately the site isn't accessible from here. It would be great if someone can put it online somewhere else or send it to me via email.

I'll also give the radeontools a try although i've not been very lucky with linux related software yet..

Sorry for wasting your time but maybe there are some other (and easier) ways to achieve my goals.

Regards,

Jochen
