Problems on acer aspire 1355xc

[Andrea Ferraresi]

Hello folks,
I'm currently experiencing a problem with my Acer 1355xc laptop. My AMD 2600+ processor works only @796mhz instead of 2.0 Ghz. I've tried to compile the kernel in many ways but the cpu still doesn't work. It works well only with ubuntu. I know that they use a lot of patches for ACPI, but i don't know which patch i need to use. Could you help me?
I'm currently off-list please reply me in cc
