2009-01-02i8k: Add Dell Vostro systemsFederico Heinz
This trivial patch adds support for i8k on the new Dell Vostro models. I tested it on my Vostro 1400, and it works. It does print a warning when loading the module: i8k: unable to get SMM BIOS version But I couldn't figure out how to fix that. The module seems to work fine, anyway...
