It's working OK for me (after fixing the mistake pointed out above).

Ambient and SODIMM look swapped - but it's probably just another Dell
error. I really need to look at getting coreboot on this thing.

The only change I'd suggest is not to change the tristate to bool for
I8K. Forcing that to bool means that SENSORS_DELL_SMM can't be
compiled as a module if the user wishes to keep i8k hanging around
"just in case". It'll probably annoy distro kernel packagers too.
Agreed. It also still needs to select HWMON (SENSORS_DELL_SMM is
only visible if HWMON is selected).
