This is a big step in the right direction.  Especially for pygrub, using
the same fs codebase that normal grub does seems like the right thing to
do.

>From a quick glance through, the changes you've made to the grub fs code
seem to be mostly eliminating grub's world of static block-access
variables and functions.  Could that be abstracted out into a wrapper
file that would let any grub filesystem code be used verbatim?  That
would reduce the maintenance load even further (and give us FAT and
ISO9660 for free).

Alternatively, how far away from stable enough are the grub2 drivers?

Cheers,

Tim.
