    Folks,

    I'm trying to port the Linux i810 Direct Rendering Interface ( DRI ) kernel
    module to FreeBSD. I have reached the point where the thing compiles, and I
    can load it as a kernel module, but it can't find the graphics device.

    Through a process of elimination I have come to the conclusion that once the
    AGP kernel module probes and attaches to the i810 graphics device, nothing
    else can attach to it. When I read the section on PCI devices it implied (
    to me at least ) that multiple kernel modules should be able to attach to the
    same device. I have tried to get it to work without any success.

    Has anyone else out there tried anything similar? If so, did you manage to
    get it to work? Does anyone have any suggestions for other things that I can
    try?

    Thanks in advance...Geoff

    BTW: I'm running FreeBSD 4.8-STABLE on a Pentium 3.
