simple, on normal systems where one can compile their own kernel, this is easy. Just compile ibm_acpi as a module. Then add ibm_acpi experimental=1 to /etc/modules.
after the system boots, there will be extra stuff in /proc/acpi/ibm. We are mainly looking at the ecdump file located in that directory tree. this file is somewhat of a live hex matrix that allows you to control some things that bios usually has control over. So many thinks to the uberness off some backwards kids we have the hex number 0x2f which is the offset for the fan controls. so when one types echo 0x2f 0x07 > /proc/acpi/ibm/ecdump we are telling the fan (offset 0x2f) to operate at it's maximum capabilities. (0x07 is for max speed)..
