2.6.33-rc3 -- Intel 945GME (inteldrmfb) -- Two Tux images displayed

[Miles Lane <miles.lane@gmail.com>]

For a long time I have gotten two pictures of Tux showing up when I
include the Tux display option in my custom kernel builds.  I don't
know how many kernel revisions ago it was when I started noticing
this.  It seems like it might have been early in the 2.6 series
kernels.

dmesg:
