Details:
This is really obscure, but I thought you might find it interesting. I'm one
of the developers with the Open Graphics Project, and we're working on a free
VGA implementation. At the moment, the card supports only text modes. No VGA
or VESA graphics (yet).
If a splash screen is specified for grub, then grub ASSUMES that the card
supports graphics and uses that to display the graphical background and UI
text. If the card does not support graphics, you get a blank screen.
For completeness and compliance, you may actually want to query the VGA BIOS
to determine if graphics is supported or not. If it's not, ignore the splash
screen entry in grub.conf.
The work-around (which isn't necessarily always possible) is to comment out
the splash screen line from grub.conf.
