Despite it's name, the 6x86 is actually a 486.

oh, more of these which I reported a while ago

wd0: interrupt timeout:
wd0: status 58<rdy,seekdone,drq> error 4<abort>
wd0: wdtimeout() DMA status 4
wd0s3a: wdstart: timeout waiting to give command reading fsbn 336 of 336-351 (wd0s3 bn 336; cn 0 tn 5 sn 21)wd0: status 80<busy> error 1<no_dam>

I think I found the cause, a loose power connector on wd0. oops :-) no
more since I fixed that :-)

Back to the point, you just need

cpu	"I486_CPU"
machine	"i386"

to define your CPU.
