The backlight of the laptop display doesn't come back on after closing and opening the lid on a Dell Latitude E6400.
This was originally reported as bug #488328 and fixed in kernel 2.6.32-15 (using http://lists.freedesktop.org/archives/intel-gfx/2010-February/005902.html), but reappeared in 2.6.32-16 (which has the 2.6.33 drm stack in it, which apparently doesn't contain this patch).
