(1) if it's truly an easier gain, the UVM + UBC are broken. I've been
pushing chuq for a while for XIP support, it's on his list to do
(2) it's a lot more widely applicable. think of just rom-ing a file
running gzipped files is a cute hack, and maybe even a useful one, but
(1) except in the case of install kernels (and maybe even
there), I don't think it's a good idea.
(2) a better, more general mechanism for doing it might be an
auto-uncompressing file system layer.
