Sensors and linux 2.6.0-test4-bk8 question

Hi,

Please bear with me and enlighten me a bit. I've been fiddling with
2.5/2.6 for some time, and got most of my hardware working (including
acpi...) better than in 2.4. (in fact now I'm using only 2.6). So now I
got to the point where I'm looking at nice-to-have stuff like sensors.

I know libsensors is not yet 2.6 aware, but I thought sensed values
where available in sysfs if one wanted to manually read them. Since I
have via hardware:

00:00.0 Host bridge: VIA Technologies, Inc. VT8377 [KT400 AGP] Host

I build-in via-pro and VIA686A:
CONFIG_I2C_VIAPRO=y
CONFIG_SENSORS_VIA686A=y

Now there is no sensor-related message as far as I can see in my dmesg,
and I do not seem to find any temperature/fan related info in /sys:

So I'd like to know how I'm supposed to check if the kernel sensors part
works (and eventualy get some useful info out of it)

You still need the bus and chip drivers before anything appears.
Which ones is basically the same as with the old lmsensors stuff, so
look in their docs.

That perl script would be nice.  You could send it to me privately or
the list if its not to big then it would be in the archives.

Thanks

An updated, documented and bugfixed version (0.02) of the program to 
report sysfs based sensors values was just put on that site.

You could try patches in <http://marc.theaimsgroup.com/?l=linux-kernel&m=106234771107439&w=2>

They slightly modify kernel sensors names and add patch to libsensors
to deal with it. You have to build libsensors using kernel 2.4 sources
still but after that it should work for both 2.4 and 2.6.

Sure there is interest:)

But how can I check the damn things work ? Sensors writers seem to 
have eschewed the nice messages every other driver writer put in dmesg to
tell me their stuff is correctly loaded.

For example I have :
"SMBus Via Pro adapter at 5000"

in "/sys/devices/pci0000:00/0000:00:11.0/i2c-3/name" so I suppose via-pro
at least is loaded (fully ?). Which should be the bus stuff I think. For
the chip stuff that would be VIA686A (?) But how am I supposed to check the 
darn thing works with nothing in dmesg ? I've already combed sysfs for clues 
and found nothing.
