Once, a long time ago, I worked with a team that built a 100%
pseudo-kernel compilation environment for driver development work
(non-Linux OS).  The idea was to develop a driver while the hardware and
kernel were still being developed.  All of the kernel interfaces that
were called by the driver were dummied up and made somewhat functional,
header files copied over, etc.

In the end, the driver wound up being a 100% drop-in-and-it-just-worked.

Perhaps there is some way to leverage User-Mode Linux for this (he says,
waving his hands wildly...).
