thanks a lot for programming the ibm-acpi support.

I guess my R31 is currently not yet supported, well since no path could be 
found ibm_acpi first could not be loaded. Without further knowledge of what 
I'm doing ;-) I added an entry for it:

char *ibm_hkey_paths[] = {
        "\\_SB.PCI0.ISA.EC.HKEY", /* X20 */
        "\\_SB.PCI0.LPC.EC.HKEY", /* X31, X40, T30, T40, T41 */
        "\\_SB.PCI0.ICH3.HKEY", /* R31 */
        NULL,
};

Could you please verify from the attached deassembled dstd if this is correct?

The next problem to load the module was docking support, though the R31 has a 
docking slot I'm not so sure if docking is supported at all.For a first test 
and to get the module loading I simply removed the hole docking stuff from 
"struct ibm_struct ibms".
This worked, but has to be improved of course.

No I can enable hotkey, but setting any mask fails:

beno:/proc/acpi/ibm# cat hotkey
state:          disabled
mask:           0000
commands:       enable, disable, reset, <mask>

beno:/proc/acpi/ibm# echo enable >hotkey
beno:/proc/acpi/ibm# cat hotkey
state:          enabled
mask:           0000
commands:       enable, disable, reset, <mask>

beno:/proc/acpi/ibm# echo "ffff" >hotkey
beno:/proc/acpi/ibm# cat hotkey
state:          enabled
mask:           0000
commands:       enable, disable, reset, <mask>


The most wanted feature from my side is certainly fan control. After I sent my 
R31 to repair last summer since it got much to hot, IBM rejusted the fan 
control which made the fan running permanently, though they only needed to 
make the cooler fitting properly on the cpu.

In v0.1 there was some basic fan control stuff, unfortunality I currently have 
no access to those sources to compare what happend with it. Is there any 
chance to get this working? As I really hate noisy fans, I'm willing to 
investigate time to get some basic fan control, I just need a pointer into 
the right direction.

Thanks,	
	Bernd
