Sorry, I failed to properly guide this bloke into filing a proper bug report. My appologies.
The card he used is as follows (lspci | grep VGA):
0000:01:00.0 VGA compatible controller: nVidia Corporation NV5M64 [RIVA TNT2 Model 64/Model 64 Pro] (rev 15)
Editing the xorg.conf and lowering the resolutions did fix the issue, so the problem is clearly the autodetect which uses too high resolutions by default.
