No AGP 8x with SiS 648 and 96.43.01 ?
Using recent 96.43.01 drivers on a FreeBSD 6.2-RELEASE system, it seems I cannot get my GeForce 4 Ti 4200 with AGP 8x actually work in 8x mode, just 4x. Neither using FreeBSD's AGPgart driver nor with builtin AGP driver. The mainboard has an SiS 648/963 chipset, which is supposed to support AGP 8x.
The same machine running Windows 2000 with ForceWare 96.71 drivers and SiS AGP drivers installed reports "AGP 8x" bus type in the control panel.
