The process of compile a new kernel

Like I said yesterday iam currently having major problems with my toshiba laptop due to the fan not working. Its topping at normale usage (So just some internet and nothing more really) at 70C, what isnt really normal.

So after trying several things, from chaging boot options to using lm-sensors to control the fan nothing untill now really worked. Partly this was (maybe? I hope so at least :)) caused by the kernel. When trying to load the toshiba_acpi module, only errors were generated,

paul@paul-laptop:~$ sudo modprobe toshiba_acpi
[sudo] password for paul:
FATAL: Error inserting toshiba_acpi (/lib/modules/2.6.31-19-generic/kernel/drivers/platform/x86/toshiba_acpi.ko): No such device
From looking at google there was no clear sign on what exactly caused this. Some say the kernel is not build with the correct modules, some say the laptop is actually not a toshiba (What I actually dont believe, but we will see :P).

So, to actually see if this is a issue, iam currently busy compiling a new kernel, like described here. To enable the toshiba functions, I need to set a option under Processor type and features -> Toshiba Laptop Support. By default (?) it was not build, so we will need to see if using that option helps to see if I can load that and after that actually have a good working fan. And maybe my FN keys are working as well after that, but thats something for the next time. Its currently for now still compiling. What, iam afraid will take some time.

However, while compiling, the temperature of the fan raised to 80C. And at this moment, the internal fan decided that its time to do some work, at full speed, to get it a bit colder. So even while compiline now, the CPU is *only* 60C. Still way to high, however, the laptop is not idle now.
