ooOO Changes to use grub2's boot configs? That sounds quite delectable! I
was planning on doing my atv 10.04 install for a minimal XBMC config, and
putting the process online. I previously sent out a tarball with some
instructions to a few people and it seems to have worked out for most people.
If you can get your changes submitted to Scott and get a new working
bootloader up, it'd make my process simpler for sure :-)
