Hi,

It seems that longhaul support in 2.6.0-test7 is still not working
properly...:-(. 


longhaul: VIA C3 'Ezra' [C5C] CPU detected. Longhaul v2 supported.
longhaul: Bogus values Min:0.000 Max:0.000. Voltage scaling disabled.
longhaul: MinMult=5.0x MaxMult=6.0x
longhaul: FSB: 0MHz Lowestspeed=0MHz Highestspeed=0MHz
