Not much activity on this list?

I fixed this by actually editing the macmodes.h file and including the
timing for this particular mode and setting it as the default mode at
boot time, but the timing seems a bit off. I only get correct timing if
I run a fbset "1280x720-50" command after a boot.

Are there any assumptions the radeonfb code does wrt to timings that
I've missed? And why does the radeonfb driver use it's own mac specific
timings? Is the old radeonfb driver better in this respect?
