Question: this may be a very naive question, but would it not make
life simpler for people if those distributing the xenify parch set
(the ones I grabbed from google) also distributed an "unmodified_drivers"
directory with the path mangling done by mkbuildtree already in place.
Then it would be simply a matter of going into unmodified_drivers
and calling a script that sets XEN= and XL= and calls make. This would
avoid the need to bring down the entire xen source, and would mean
only combining two potions, rather than three. As far as I can tell,
it doesn't actually /need/ the xen source, though I may be wrong. And
pv drivers built this way work with older versions (I've tried 3.3)
as well as Xen 4.0.

By which I mean, if this tgz
were just expanded into (say) Andrew Lyon's gentoo patch, all you would
need to do instead of my step 2 would be
 cd pvdrivers
and you'd be done. No hg clone etc.
