Deepayan's suggestion is the way to go. But in this
simple example you can just relevel the factors:

  bwplot( conc ~ relevel(Type, ref=2) : Treatment, data = CO2 )

and/or relevel 'Treatment'. This is only trivially
different from applying relevel() before calling bwplot().

(BTW: is your ":" meant to be "|"?)
