grub splash image busted?

[Tom Horsley <tom horsley att net>]

The latest rawhide /boot/grub/splash.xpm.gz file shows up
looking like a bad swatch of carpet with vomit stains when
grub tries to display it :-).

I thought splash images were restricted to 14 colors (or
some number around there), this image has 255 colors according
to identify (ImageMagick command).
