You need a driver that will power down the PCI device.

That boot parameter has nothing to do with suspend (the only code path
it's involved with is run on resume), so I doubt that.

If the s3_bios option works, then vbetool will probably work as well.

We need some sort of solution for this. It would be easy enough to write
a PCI driver that binds to any video device and puts it into D3 on
suspend.
