PPC DRM graphics testing

[Michael Copeland]

After doing some reading, the mac edition of this card does not have the
rom on it, appears to be in the os x driver itself, and is downloaded to
the card when xnu kernel boots. So, if you don't have a 10.5.8 install disk
handy, I'll dig mine up and install it on mine and see about ripping the
rom out of there. You will have to modify the driver to use this rom, as
I'm certain it's quite dissimilar to the pc version of the rom.
