quake3, ut2004 and xrandr

[TheCoop]

Does quake3 and ut2004 support changing resolutions using xrandr? The reason I ask is that i've got a strange lcd on my laptop that only works in 1680x1050 in the 'old' resolutions, which is not helpful for playing games, but xrandr succesfully changes resolutions to normal ones. Will Q3/UT2004 attempt to change res using the old method, or just use the xrandr resolution I set before I start it (with the right config ofc)
