Yeah, I know. The list of issues with our ref implementation is not
limited to the kernel. Seriously, we're using 2.95 as our compiler. Some
of the stuff we want to do doesn't even build with that quite right.

Thanks. We're looking at some of the later packaged stuff from David
Woodhouse's webpage (I believe) to see what is required. Given the choice,
I would like to migrate the whole subsystem, but that might cause
problems, so it's gonna take some investigation.

HW supplier won't budge. You might be surprised at how many devices are
floating around sporting this ref design that they still support. I have a
better chance of reimplementing this entire platform on my own than
getting them to migrate kernels.

Which is a thought...
