Hmm, then it was probably not there in the old platinum.c file or I missed to
copy it. But the comments at the top are correct, platinumfb is based on the
controlfb driver, not on the old platinum.c. I only ripped out and modified the
hardware info from platinum.c. And why didn't you stand up ~1 year ago, when
there was lot's of discussion on the lists about the platinumfb and controlfb
drivers? Dan and I could have need help back then.

I'm still on my 7200/75 too :-), I just switched a ATI Xclaim3D, cause it's
cheaper to get such a card than to upgrade videomem. That explains why 16bit
and higher modes possibly don't work correctly, it's simply because I can only
test with 1MB on platinunm.
I know only about 3 problems right now, the
color scaling, a typo in the invalidate_cache macro, it should
use dcbf instead of dcbi. Both I haven't forwarded yet to Geert.
The other one is that 832*624*16 won't work with 1MB videomem, cause I had to
align the framebuffer on a 4K boundary.
Feel free to fix platinumfb as you like, including the copyright. In
fact I would happily hand over "maintainership" to you, as I currently don't use
platinum anymore, except for testing. BTW, what did you test? console, Xpmac or
FBDev?
Franz.
