Heh, that is a weak point of netcfg. Documentation is between incomplete
and non-existent.

netcfg uses wpa_supplicant for the configuration of the wireless
connection. Remove your PRE_UP and try ADHOC=1 as an option
(undocumented, I think, probably also untested).

No idea, must have something to do with pppd options (maybe netcfg sets
'demand').

This should be improved to provide a 'pppoe' connection anyway.
