[lm-sensors] BIOS Corruption (was : new abituguru driver in mm

Err, this is bad :(

Hans, see why I was reluctant to having your driver in the kernel tree?
Nothing personal, but that kind of problem is to be expected when
writing a driver without a datasheet :(

What should we do now? Mark the driver broken in the kernel tree?
2.6.18 is just around the corner, and we sure don't want people to
corrupt their BIOS.

Sunil, did you try a complete power-off (with PSU switched off or
unplugged) to see if the default values are back?
