This sounds like my problem too ;)

The problem for me and you too is, that your display is detected as a 18bit
display.

==== snip ====
(II) RADEONHD(0): FUNCTION: RHDAtomBiosFunc
(II) RADEONHD(0): FUNCTION: rhdAtomLvdsInfoQuery
(II) RADEONHD(0): LVDS 24Bit: 0x0
(II) RADEONHD(0): FUNCTION: RHDAtomBiosFunc
(II) RADEONHD(0): FUNCTION: rhdAtomLvdsInfoQuery
(II) RADEONHD(0): LVDS FPDI: 0x490
(--) RADEONHD(0): Detected a 18bit dual link panel.
==== snip ====
last line ;)

This is the first problem. The second problem is the dithering seams to be not
correct for 18bit.
I send a mail to the mailing list with a correcting patch. I think it looks
better with this patch. But the patch doesn't solve the detection of the panel
as 18bit.
