Then your problem is related to 544155, they've some other ATI mobility
graphic chip and get an unaligned pointer when gfxterm is enabled.

I'd be glad to, if I knew how. :P

Upstream's repo is:
svn://svn.sv.gnu.org/grub/trunk/grub2

Then either get the Debian source package and copy over the debian/
directory or follow the steps in the Debian wiki to check it out from
our Debian repository:
http://wiki.debian.org/de/GRUB2/Anleitung/DebianPaketVonOriginalQuelltext

I also suggest to edit debian/control and remove every package you don't
need, i.e. keep first block, grub-common and grub-pc and remove
everything else, else it needs very long to build.
And then use svn-bisect like you said.
