Problems with ASUS A3G

Hi,

I'm new to that list, so thank you for reading this.

I have an ASUS A3843GLP driving with a 2.9.11 kernel. I patched the kernel as mentioned on http://acpi.sourceforge.net/download.html
Problems are:
- fan almost always running on lowest level
- speed step control fails when using kpowerd (no speed step, CPU runs on 1700 MHz all the time, but acpi -V reports that the CPU runs on 50%)
- writing different temperature levels to the thermalzone is accepted but ignored. Fan still runs even if temperature of CPU is below 50°C

For testing I installed Windows and got the fan deactivated using SpeedswitchXP (Power4Gear didn't make it for me). Since I had no experience with ASUS notenooks I now know that it is possible to throttle down the CPU to 600 MHz and having the fan NOT working. So, is there a way to configure acpi that this is also possible with Linux?

thanx for help,
Mirco
