>Description:
	Additional PCI ID to attach sisdrm to SIS622 integrated VGA
>How-To-Repeat:
	For example on the Intel D201GLY2 (essential) board you can find the SIS
chipset. DRI is disabled when starting Xorg because there is no drm device available.
After adding the PCI ID DRI can be used.
But it sometimes isn't beneficial. If the CPU is idle otherwise, glxgears shows 270fps
in SW rendering compared to 170fs with DRI enabled.
On the other hand if one can accept this extremely wimpy 3d acceleration, the CPU
can have some more cycles for other tasks... I think supporting DRI is perferred, DRI can
be disabled in Xorg config.
