Hi, I have a Tyan S2895 (Thunder K8WE) motherboard, and the
recently-added nfsmb driver attaches. However, I don't know which
i2c device (if any) is appropriate for this board. The manual
<http://www.tyan.com/manuals/m_s2895_101.pdf> says:

Sensor chip: LM95221 (SMB address: 010 1011x)
CPU1 temperature: U92 pin1, 2
CPU2 temperature: U92 pin3, 4

FAN speed detect and control
CPU1 FAN PWM: SIO PIN34 GP11
CPU1 FAN TACH: SIO PIN7 GP85
CPU2 FAN PWM: SIO PIN43 GP22
CPU2 FAN TACH: SIO PIN110 FAN_TACH4
FAN1 PWM: CK804 PINAB4 FANCTL1
FAN1 TACH: CK804 PINAA3 FANRPM
FAN2 PWM: SIO PIN104 GP74
FAN2 TACH: SIO PIN35 FAN_TACH2
FAN3 PWM: SIO PIN104 GP74
FAN3 TACH: SIO PIN103 FAN TACH3
FAN4 PWM: CK804 PINAA2 FANCTL0
FAN4 TACH: CK804 PINAA3 FANRPM

Apparently, "SIO" refers to the LPC Super I/O chip, and "CK804" is one
of the nForce chips.

Is there a driver that will get some/all of those temperature and fan
speed sensors working under NetBSD?
