Grub 1.98 comes with the gfxmenu patch. The code used to include the
entries in 00_header currently only adds the theme name, but nothing
else. Due to either a bug or feature, currently grub do not load
dependencies automatically. This means that when using a theme, it
will not load the image modules or fonts required by the selected
theme, causing it to fail to load at all.
I included a patch that searches the theme directory, and add the
entries just before the theme file.
How to reproduce:
1. Put a GRUB_THEME entry with your theme in /etc/default/grub.
2. Generate your grub.cfg with grub-mkconfig
3. Reboot
4. The theme will not load at all.
The patch was tested against both grub 1.98 and trunk r2263
