Where are you seeing background_dhclient_fxp0 being set?

Oh, that's a bug in /etc/defaults/rc.conf I think.  It shuoldn't have that 
entry set, or it should be set to either YES or NO, not empty.  So, you have 
to have 'fxp0' to see this warning.  The setting of 'dhclient_flags_fxp0' is 
also bogus.  I think these are intended to be examples in which case they 
should be commented out like other examples in this file.  I think this is 
the better fix, and that your network.subr change should be reverted:

Having pppoed_interface default to fxp0 is also likely a bug.  It should 
probably be unset, and the rc.d script should require it to be set if pppoed 
is enabled.
