fan issues

simple, on normal systems where one can compile their own kernel, this is easy. Just compile ibm_acpi as a module. Then

echo "ibm_acpi experimental=1" >> /etc/modules

after the system boots, there will be extra stuff in /proc/acpi/ibm. We are mainly looking at the embedded controller register dump (ecdump)file located in that directory tree. this file is somewhat of a live hex register that allows you to control some things that bios usually has control over. So many thanks to the uberness off some backwards kids we have the hex number 0x2f which is the value for the fan controls. so when one types:

echo 0x2f 0x07 > /proc/acpi/ibm/ecdump

we are telling the fan (0x2f) to operate at it's maximum capabilities. (0x07 is for max speed)..

though i have only read about this. One could pass the

experimental=1

argument on the boot line for the kernel, if the module is--and which happens to be--built-in. though i don't have the syntax for such thing in my head right now... tsk tsk tsk.
