I tried it - i.e. I replaced pc87427.c in a copy of the directory
containing the old pc87427.c
But I regret to report a failure. I try to document the relevant things...

Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-i801' for device 0000:00:1f.3: Intel 82801EB ICH5

We will now try to load each adapter module in turn.
Load `i2c-i801' (say NO if built into your kernel)? (YES/no):
FATAL: Module i2c_i801 not found.
Loading failed... skipping.

Driver `pc87427' (should be inserted):
  Detects correctly:
  * ISA bus address 0x0840 (Busdriver `i2c-isa')

To load everything that is needed, add this to some /etc/rc* file:

#----cut here----
# I2C adapter drivers
modprobe i2c-isa
# Chip drivers
modprobe pc87427
# no driver for Nat. Semi. PC87427 Super IO Health Sensors yet
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----

(MK tries it)
[root at matrix PC87427-platform-driver]# modprobe i2c-isa
[root at matrix PC87427-platform-driver]# modprobe pc87427
[root at matrix PC87427-platform-driver]# /usr/local/bin/sensors -s #
recommended
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Nothing happens yet in syslog or dmesg
As soon as I execute 'sensors' with the config below, I'll reveice these
lines in dmesg:

I hope, I didn't miss anything ...

By the way, I found that sensors-detect now detects a PC87360:
Found `Nat. Semi. PC87360 Super IO Fan Sensors'
    (but not activated)
If I try a 'modprobe pc87360' I get
FATAL: Error inserting pc87360
(/lib/modules/2.6.16-xen/kernel/drivers/hwmon/pc87360.ko): No such device
pc87360: Device 0x09 not activated
pc87360: No active logical device, module not inserted.

I don't know if it's somehow related. I think, it finds it at least
since the snapshot you published recently. It definitely didn't
recognize before.

Tell me if I can do / find out more for you...

Regards - Michael
