done that, and talked on IRC with some debian-arm developers and Kero,
and it seems that noone is using 2.0.x on arm, these days. So in order
to make maintenance easier, I propose to remove the support for that,
and simply make it work with the current kernels. Unfortunately,
handhelds.org seems down, and HP's testdrive seems to have taken offline
their arm machines, so I don't have a box to test on atm.
