Re: intelfb does not work with i915

["Buttchereit, Axel (XL)" <xl@xlsigned.net>]

Hi,

this weekend I'm going to switch the kernel version on the computer
that I used to develop the patch from 2.6.10 (+ original patch)
to 2.6.12(-gentoo-r4) and give (you) a feedback.

ByTheWay:
  16 Bits per Pixel does not work on my computer, too.
  Have you tried a 32 Bit mode, e. g. 1024x768-32@70?
  (This should be the default mode.)

Cheers,
Axel
