Same here.  I've seen it on both my laptop:

00:02.0 VGA compatible controller: Intel Corporation Mobile 
GM965/GL960 Integrated Graphics Controller (rev 0c)
00:02.1 Display controller: Intel Corporation Mobile GM965/GL960 
Integrated Graphics Controller (rev 0c)

and desktop:

01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon 
X600 (PCIE)]
01:00.1 Display controller: ATI Technologies Inc RV380 [Radeon X600]
