...does not support AGP cards but has AGP capability (for the onboard video). At least PC Chips A31G board using this chipset has an AGP-like AGPro slot that's wired to the PCI bus. Enabling AGP will fail (GPU lockup and software fbcon, X11 hangs). Add support for matching just the host bridge in nvkm_device_agp_quirks and add entry for SiS 761 with mode 0 (AGP disabled).

Hello, I have a PC Chips A31G board with AGPro slot and found that nouveau does not work properly with it. Console works but reverts to software mode, X11 hangs with mouse cursor only. The slot is physically AGP 1.5V but is wired to PCI bus as the chipset (SiS 761) does not support AGP cards. To further complicate things, the chipset has AGP capability - but only for the integrated video. You can

Hi guys, Well let's face it AGP is a total headache to maintain and dead for at least 10+ years. We have a lot of x86 specific stuff in the architecture independent graphics memory management to get the caching right, abusing the DMA API on multiple occasions, need to distinct between AGP and driver specific page tables etc etc... So the idea here is to just go ahead and remove the support
