Due to a bogus FBC support check and failing to check for FBC support in the right places, mode setting on non-mobile platforms could fail and hang in the FBC disable routine. Fix it up. This fix highlights the need for cleanups in this area (function pointers and better feature support checks). Patches for that to follow. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
