Hi!
  I run the exact setup Mr. Hamblen described, using the ATI proprietary
driver Mr. Harris mentions. It works great, though it's a pain in some
ways. For instance, you have to re-compile it each time you install an
updated kernel, and the RPM contains files that conflict with XFree86
MesaGL, so I had to --force --nodeps it (suggestions on what I SHOULD
have done are welcome, RPM is still a little mysterious to me). If you
really want dual-DVI (with hardware, even), you might want to consider
going over to the dark side and try the ATI driver.
