Hi Juerg,

Unfortunately that didn't work:

root at ythekshri:~# modprobe  dme1737 force_id=0x7c
FATAL: Error inserting dme1737
(/lib/modules/2.6.31-16-generic-pae/kernel/drivers/hwmon/dme1737.ko):
Device or resource busy
root at ythekshri:~#

dmesg reports:

[ 1793.870444] ACPI: I/O resource dme1737 [0xa70-0xa71] conflicts with
ACPI region RNTR [0xa00-0xa7f]
[ 1793.870448] ACPI: If an ACPI driver is available for this device,
you should use it instead of the native driver

root at ythekshri:~# cat /proc/ioports | grep a7
0a00-0a7f : pnp 00:09
root at ythekshri:~#

Cheers,

Marcus.
