This is what I expected. Looking quickly over the prep_* files in

Just to make sure I tried hard enough.

Well, "not too hard" is a bit funny, since I'm a kernel hacking newbie!
But I guess I should be able to try that 2.4.2 kernel to verify this
patch works, and then try to to stick that stuff into a more recent
(2.4) kernel. I'm not sure if I can support that platform in the long
run, since this (at the moment) a rather limited project - get the
platform running, get board capabilities running, get VME bus running -
produce a demonstration and document that solution as a simple BSP.

Thanks for the advice, and I think I have little other choice than
heeding it, because I'm starting to run out of options. ;)
