you don't need to worry about it.  If your kernel prints out:

	cia0: WARNING: Pyxis pass 1 DMA bug; no bets...

...than CCF_PYXISBUG is set already :-)

It's set in cia.c, when the core logic chipset is attached, based on
the revision of your workstation's mainboard.  I.e. if it's < Miata 1.5
(which is the first rev to have the bug fixed), then it gets set.
