Also happening here on a Dell Latitude D800. Confirmed that my Vendor is "Dell Computer Corporation" also.

On my system, at least, a variant of Rich's workaround is serving me just fine. I added the following to my ~/.xmodmaprc :

keycode 232 = Shift_L
keycode 233 = Shift_R

This prevents those keycodes from triggering the Gnome Brightness Applet entirely, which seems to bypass the problem. The screen brightness still changes. I think I personally may keep this enabled even after this bug gets resolved. I see no value in having a little slightly-out-of-sync bar graph pop up to tell me how bright my screen is anyway; my eyes will serve that purpose just fine. :)
