Cool -- that was quick work.

I see that the linux domain building routine was close enough to
what you needed, so you didn't need a NetBSD specific routine.

How do you think it best to distribute this stuff?  We'd be
happy to put whatever you think appropriate in to the Xen tree.

Oops. A couple of embarrassing ones there... 
I've applied the fix to the 1.2 tree and pushed it to
bk://xen.bkbits.net

Fortunately, the bug had already been expunged in the 1.3 tree
thanks to a complete rewrite of that bit of code.

Cheers,
Ian
