Tony, go here: http://www.csd.toshiba.com/cgi-bin/t..._sc_modSel.jsp
and then select the M400 in the right pane. Then use Search with Ask Iris
(R) on "Vista drivers" without the quotes. You'll get 34 results, including
the top one which is "Windows Vista and Toshiba computers - drivers, BIOS,
and other information" which is good reading material so you know what's
going on.

In the listed downloads (below the above) are various drivers for Vista, all
released by Toshiba in mid-December. Make sure to note the release date and
version of each, so you get the latest ones. Also keep in mind, if you're
still running Vista RC1 you might just want to wait for the actual Vista
release.
