Well the minimum `patch' is indeed only the new rpc_machdep.c from
-current. This will work on its own. You can unset COMPAT_OLD_BOOTLOADER
to only get the new bootloader without any compatibility stuff added to
it.

Yikes !!! Hmm.... the safest way is propably to increase the WimpSlot in
wich the program runs; I think it might be a bit too short. I've been
working on a better detection mechanism for `out of pages' but am
distracted for now for work on wscons.

Could you please try it with a bigger WimpSlot ? and please download the
latest version of the new bootloader; lots of bugs have been fixed.

Cheers,
