PATCH 1/1 Add VX800/VX820 support to i2c-viapro

Hello,

Thanks to new datasheets published on http://linux.via.com.tw we can now add support for VX800/VX820 chipsets.

If anyone has the hardware, please test the patch in attachment. Some simple test with i2cdump should be enough the hardware controller is same as on other chipsets.

Thanks. I've queued this patch for 2.6.28, so it's in linux-next now. I hope we can get some testing feedback in the next weeks.
