lm-sensors with msi 890fxa-gd70

[QuantumFoam]

I'm running xubuntu 11.04 on the MSI 880fxa-gd70 motherboard. Recently had my AX1200 fail with low voltage (they said a capacitor probably went bad), which corsair replaced for me. I'd like to periodically check the power supply voltages under load so I can ensure they're within spec. Unfortunately it appears the sensors package doesn't support the chipset on the MSI board, so I cannot get any power supply voltage information from it. Is there any way to fix this without upgrading to a newer version of xubuntu? From my searches on the problem it appears that's the only solution, and I don't want to do that because of issues with the opencl SDK version and loss of performance under the newer ati drivers (along with the 100% cpu bug problem).
