I thought that the PCI bus clock was always either 1/3 or 1/2 of the FSB
clock (depending on whether it's closer to 100Mhz or 66Mhz), meaning that
any time you set the BIOS to a clock frequency other than 100 or 66, the
PCI clock would be at something other than 33Mhz. For example, I usually
run my BP6 FSB at 82Mhz (yielding 451Mhz from 366Mhz-rated parts), so my
FSB would be 41Mhz (I think the switchover to 1/3-FSB happens at a higher
speed). Note that running at this speed gives me problems with some PCI
peripherals (in particular, all vintages of NetGear FA310-TX), a good
indicator that the PCI clock is modified.

(note that I haven't tried the HPT366 controller under NetBSD yet.)
