A lot of dualhead cards show up as two devices to deal with a
limitation of the Windows 2000 driver model.  Such is the case with
Jan's card:
01:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60
[Radeon X300 (PCIE)]
01:00.1 Display controller: ATI Technologies Inc RV370 [Radeon X300SE]

The first one (01:00.0) is the actual device, the second (01:00.1) is
a placeholder for windows 2000.
