pygrub output should be in the xend logs, it includes the command line
so you can copy that and run by hand in domain 0. Also you can run the
individual pygrub modules (e.g. GrubConf.py) on a config file extracted
from a guest to see if it works as expected (see the end of the file for
the syntax).
Do you know if FC12 uses grub1 or grub2?
IIRC the recent patches were all to grub2 specific code paths.
