Yeah, that's how I got Fedora running on it (I think the people who did the
Fedora spin for the chromebook chose the google kernel for exactly
the reasons you mention above). It felt a little sluggish for a native
kernel build though, and I'm not setup for cross-building so I stuck with
the 3.4 build.

It blew up in a minute or so of runtime when I tried last week.

Feel free to mail me off-list if I can do anything to help out, though
hopefully things should build & run 'out of the box'. You shouldn't
need any special command line args (though you might get inspiration
for ideas from the scripts/test-* harnesses)
