I have a T20 which is still in use and going strong. I came accross this during a fresh install and have tried the patch out but there were 2 problems:

1. The VENDOR_ID/DEVICE_ID calls need to be compared against.. well.. the vendor & device IDs not the subsystem IDs

2. drmAgpVendorId and drmAgpDeviceId calls both return 0 because the AGP fd has not yet been initialised.

I was able to fix 1 easily, but I'm not sure whether there is a good way to get the Agp device details before it has been initialised.

I've attached an updated patch with the Agp bits commented out and IDs corrected. With these, it works for me but I guess it needs the Agp bridge test again to make sure it doesn't any working hardware.
