Yes.

What kind of blank is it? Do you see the mouse pointer at least? Do the
monitor(s) stay on or do they go into standby mode? I've had issues with
radeon in the past, and after asking in the mailing list it seemed like
some issue with my AGP card. Some developer suggested to try this in the
xorg.conf file and it worked for me:

  Option      "BusType" "PCIE"

And yes, it's an AGP card. The logic behind this is out of my
understanding. You can see the thread here:

http://article.gmane.org/gmane.comp.freedesktop.xorg.drivers.ati/10628/match=i92guboj

If you have problems with the radeon (not fglrx or radeonhd) driver, I
suggest posting to that list. It's probably the best place to get help if
the standard procedures do not work.
