Looks like my i965 based laptop is not happy with this patch(well, the
version in erics repository). I get a black screen on LVDS(although
backlight works as always).

The problem is not necessarily the inability of that chip to handle LVDS
on pipe A: The dot clock differs according to intel_reg_dumper, and i
get a new warning.

Output of intel_reg_dumper with and without this patch is attached.

Regards,
  Pierre
