Just for reference, I pushed it out to git://git.kernel.org:/pub/scm/linux/kernel/git/geert/linux-m68k.git uamiga-untested http://git.kernel.org/?p=linux/kernel/git/geert/linux-m68k.git;a=shortlog;h=refs/heads/uamiga-untested It's not identical to what I tested, and some work is required to rebase it to 3.0-rc1, due to changes in the m68knommu handling.
