I went on the conexant website and they actually assured pin for pin
compatability. Feeling confident, I went into /usr/src/sys/dev/bktr/bktr_reg.h,
changed the 878 entry to 0x036c, then that didn't fly. It booted, then I did
a pciconf -lv, and the line was "chip=0x016e109", so I was like... change the
entry in 878 to 0x016e... crash on boot. Tried it again on 879 and that
didn't work either. Crash on boot. I haven't tried taking it out of the
kernel and loading it as a module, but I suspect the results would be the same.
So much for the chips touted pin for pin compatability with the older
versions...
If anyone would care to look at the -current archives, I remember Doug White
responded to my request saying that it wasn't so straight forward as to add in
the pci id. I don't know what else to go from here. conexant's website does
post the references for the chip, I don't know if they are at all helpful.
Many thanks though, I'm sure it will work itself out sooner or latter.
sincerely,
