Hey Stephan,

The BSSID can be just about any random number, but two bits need to be
set.  So its easiest just to start with 02: then choose the rest.  BSSID
of all 0s should cause it to try to find an existing adhoc network to
associate with.

I think you'll be interested in Commotion MeshTether, which is an
Android app for OLSR, based on olsrd.  We're trying to automate the
whole adhoc setup.  I've been testing on HTC with Android 2.3 mostly, so
it would be good to have testing on more platforms.

As for setting up adhoc mode manually, I've had the best luck using
'iwconfig' from a Debian chroot using LilDebi:
