sensors not working on VIA board

hi,

just installed obsd 4.0 on my new via-based system (jetway j7f4k
board), and everything is working perfectly, but not the sensors. it
has them (at least the POST shows all the readings), but it seems
no driver is detected by openbsd (hence no hw.sensors are seen by
sysctl). is there another way to get sensor-readings for this board ?
(via smbus, iic, apm or something). i must admit all the terminology
is mostly greek to me, on my old p3 system the sensors 'just worked'.

dmesg is shown below, entries i think are useless are removed for
brevity. the entries that look suspicious to me are :

pcibios0: bad IRQ table checksum
doesn't seem to be a problem, but still...

bios0: ROM list: 0xc0000/0xfc00 0xd0000/0x5000!
an exclamation mark ? why's that ?

viapm0 at pci0 dev 17 function 0 "VIA VT8237 ISA" rev 0x00
iic0 at viapm0
"unknown" at iic0 addr 0x18 not configured
could this "unknown" be an unsupported sensor-chip ?
