Longhaul support for Via C3 (samuel 2) CPU and Via prosavage PM133 northbridge

Longhaul support for Via C3 (samuel 2) CPU and Via prosavage PM133 northbridge

[sylvain]

Hi,

I try to use cpufreq with a Comwell Lv602 motherboard ( VT8605 [ProSavage
PM133]) and a Via C3 (samuel 2) CPU.
I have a 2.6.22.6 kernel with C3 longhaul (CONFIG_X86_LONGHAUL=y) set.
Unfortunatly, at boot time, I get the messages:

CPU: Centaur VIA Samuel 2 stepping 03
[...]
longhaul: VIA C3 'Samuel 2' [C5B] CPU detected.  Longhaul v1 supported.
longhaul: No ACPI support. Unsupported northbridge


Does it mean that this motherboard is not supported, or I missed something?

Thanks

Sylvain

Northbridge has AGP/PCI arbiter disable bits, but support for this 
northbridge was never tested. Let me know if You are interested in 
testing it.
