Cross-building on ubuntu

[David Forbes <ilikeearlymornings%yahoo.co.uk@localhost>]

All,
 
I've recently being trying to cross-build NetBSD from a
ubuntu 8.10 system.  In general, the build.sh system works
well and I've managed to get it working to the point of
a building a usable i386/GENERIC kernel.
 
However, I did have to solve a number of snags along the
way, to which the solutions were in varied locations across
the internet.  Is there a document/wiki that I should
contribute my notes to?

Regards,
 
David.
