I agree with you. I suggested Scratchbox exactly because we want
something done to play with initially ;). Fixing packages to
cross-compile properly would be IMHO the correct long term solution.
BTW, I've received suggestions to consider OpenEmbedded[1], but I know
nothing about how it works.

How does it work specifically? Does It run the test program on the
target/emulator? Or does it simply compile for the host and run it?

I would appreciate a copy of such patches (although I'm afraid I may
not play with them these days, college exams...).

What about building the initial base system in both Scratchbox and in a
traditional cross-compiling environment (e.g. plain
dpkg-cross/dpkg-buildpackage or Slind) and doing some comparisons? We
would then evaluate how much work is necessary to get the fixes done
for a small set of packages such as ubuntu-minimal (which I assume is
small enough to build in a few days).

I can give a try on Scratchbox, any volunteers for other build systems?
