Hi,
I recently bought an Acer Aspire 5051 / 5050 with an AMD Mobile MK-36 cpu.
((( Turion 64 "Richmond" (90 nm)
* All models support: MMX, SSE, SSE2, SSE3, Enhanced 3DNow!, NX bit, AMD64
(an x86-64 implementation), PowerNow!, AMD Virtualization
Model Number Frequency L2-Cache HyperTransport Multiplier Voltage TDP Socket
Release date Order Part Number
Turion 64 MK-36 2000 MHz 512 KiB 800 MHz 10x 1.15 V 31 W Socket S1
TMDMK36HAX4CM )))
I tried several linux versions: Opensuse 10.1 beta2, Fedora Core 6,
archlinux 0.7.2 all with latest kernel versions (2.6.18), also x86_64
compiled ones, but there were no C-states for throttling available. ( Yes, I
modprobed all acpi modules, powernow-k8, ... )

I googled but found no information.
I came to http:
acpi.sourceforge . net
- The test results also say that there is no throttling support ?
- That cannot be true ? Hopefully.
- So, what do you say ?
- Will there be support in future kernel releases ?
- What is the current status ?
