Shouldn't be a problem as long as the DOS partition table vs. 4 KiB
sectors thing is fixed.

I don't think ubuntu has adopted any of the relevant updates yet.
I believe the Fedora 13 Alpha is due to be released this week. That
would be the best test platform because several of the people who have
been actively engaged in the 4 KiB sector enablement process are Fedora
developers.
