Exactly. It's called 'consistency'. ;) There is no depth 32 currently (because
only 24 bits are actually used) but the default for depth 24 is 32 bpp for the
r128 driver.

Yeah, that's why I was surprised that you still seemed to confuse them. Sorry
(or rather glad) if you didn't.

Seemed strange indeed. So I just looked at the source again and saw that I had
forgotten something. "UseFBDev" only works if you specify the bus ID in the
Device Section, like
BusID "PCI:0:16:0"

You're lucky then. For the longest time we thought it wouldn't work without
"UseFBDev" at all.

I don't understand why you need a modeline at all. But there's no point in
arguing over that of course. ;)

You said in an earlier post that "ProgramFPRegs" "No" killed the display, is
that no longer true?
