1600x1200 resolution breaks at startup, but works later with xrandr

I have a large CRT monitor with a maximum resolution (as claimed by EDID) of 1600x1200. If I try to start X with an xorg.conf that requests 1600x1200 as the initial resolution (or if I start it without an xorg.conf), then the server crashes with
(II) CHROME(0): Required bandwidth is not available. (576000000 > 553000000) (II) CHROME(0): ViaDisplayDisableCRT (EE) Fatal server error: (EE) AddScreen/ScreenInit failed for driver 0
However, if I start X with an xorg.conf that requests a lower resolution (e.g. 1280x1024), and if I later request 1600x1200 with
$ xrandr --output VGA-1 --mode "1600x1200"
then the server accepts and switches to the higher resolution without complaint.
