I prefer to stick with 37.5MHz PCI bus (75MHz mem. bus) since all my
PCI cards are comfortable with it. :-) Of course, yes, you need to be
in the experimenting mind-set before setting out on such a task...
FWIW, this is with a FIC PA-2007 (VIA VP2 chipset), which works quite
excellently with NetBSD.
