I've thought, before to try to find out the problem, if the tuning of
minimal distro for ARM architecutes would be the Angstrom
distribution.

By the way, I'm trying to use the minimal distro for Beagleboard,
instead of Angstron, because of I have thought minimal distro is a
good point of start a fresh (o vanilla) basic distribution, and
Angstron is a more complete and cutting edge distribution for
Beagleboard platform (as Koen has told me).

Thanks.
