Fwd: Dell PowerEdge 400SC fan speed monitoring

I've got a Dell PowerEdge 400SC running 5.3-BETA2 nicely, and I'd like
to be able to monitor the internal fan RPM, if possible. The PE 400SC
motherboard is very similar to an Intel D875PBZ. I've added the
following SMBus options to my kernel:
# smbus interface to Intel ICH5 management
device smbus # Bus support, required for smb below.
# IIC devices to support motherboard monitoring
# devices I've added at the suggestion of Google and man pages:
But none of the fan speed monitoring ports I've tried will give any
useful results for fan speed. I've installed sysutils/xmbmon, which
gives reasonable looking values for the chipset, motherboard, and CPU
temperatures (95, 104, and 88 degrees F, respectively), but lists fan
speed as "0". sysutils/healthd, when run in non-daemon mode using the
SMBus, reports tempertature at 0, 0, 0, and fan rotational speed at an
unreasonable-looking 0, 22500, 9642. sysutils/consolehm won't compile
in SMBus support unless I symlink /usr/include/dev/smbus/smb.h to
/usr/include/machine/, and then it reports 40.0 degrees C for all 3
temperature sensors and some wacky numbers for fan RPM like 8k, 33k,
Is anyone else able to monitor their PowerEdge 400SC fan speed(s)? Does
anyone have suggestions for getting this working? Am I just chasing my
tail with this? Tune in next week as we present the next gripping
episode of ... As the server turns!
