Probably could be supported by geodeide(4) or viaide(4)

No, that's not it, there is no driver attaching at all.

This means that neither exception 16 or interrupt 13 is working.

Bit 5 of CR0 looks interesting (not that I know anything).
Bit 13 of XC_MODE_MSR.
XC_HIST_MSR.
Bottom half of page 558, AMD publication 33234D.

Also it appears the SATA, and a few other misc things aren't
configured.

There appears to be documentation on the security
