So none of the patches looked scary to me, but then, neither did
earlier versions.

It's the testing that worries me most. Pretty much no developers run
32-bit any more, and I'd be most worried about the odd interactions
that might be hw-specific. Some crazy EFI mapping setup or the similar
odd case that simply requires a particular configuration or setup.

But I guess those issues will never be found until we just spring this
all on the unsuspecting public.
