Bug#620359: background_image not show in 1.99-rc1 if gfxmode=640x480

Fri Apr 1 11:07:03 UTC 2011

Package: grub-pc
Version: 1.99

The background_image not show in 1.99-rc1 if gfxmode=640x480, but it's
fine if gfxmode=800x600 or gfxmode=1024x768. Tested in many computers.
The background image size used is 640x480 and png format. The system
is Debian with grub-pc 1.99~rc1-6 (the same with all versions
1.99~rc1-X). In previous versions, 1.98 and older, it was ok.

Only the marc is showed, the rest is black background. Only Debian
version afected.
