Bug#520846: grub-ieee1275: update-grub fails due to no suitable gfxterm module available

[Jordi Mallach]

Package: grub-ieee1275
Version: 1.96+20090317-1
Severity: important

The latest version of GRUB works a lot better than previously out of
the box, but I've found the following regression:

jordi at horta:~$ sudo update-grub          
Generating grub.cfg ...
No suitable backend could be found for gfxterm.

Due to this, no grub.cfg is generated. For now, I've just worked around
this simply replacing the exit 1 with an exit 0 so the script continues
building the config file.

This should be special-cased for PPC as long as gfxterm doesn't work on
this architecture.

Thanks,
Jordi
