>Description:
Environment:
  - Motherboard ASUS K8V-X SE
  - Graphics (no-name) ATI 9250 (probes as PCI id 1002:5960, with a
    secondary card as 1002:5940 - see below)
  - Running RELENG_6_0 as of 2005-10-30, in i386 mode (not 64 bit)
  - Running XORG-6_8_99_901

Problem:
  - Enabling DRI in the X server freezes/hangs the system

Possible cause:
  - I have a feeling that it is either wrong or not enough to set
    the K8T880Pro CPU to PCI Bridge (1106:0282), as seen from dmesg.boot.
    There still is the Apollo K8HTB CPU to AGP 2.0/3.0 Bridge (1106:b188),
    and it seems that nothing in the kernel sources touches/sets that.
    Could some insightful soul please look into this?

Comments:
  - What is intriguing to me is that a very similar PCI id of 1106:3188
    is also handled in agp_amd64.c, but the (again similar) PCI id of
    1106:3189 is handled in agp_via.c. I am wondering what would happen
    if I just commented out both 1106:0282 and 1106:3188 from agp_amd64.c,
    and added the latter to agp_via.c. But I don't really dare doing this
    for fear of burning up my hardware.
  - On Linux, the system freezes both with the Xorg stuff (but this then
    is only SuSE 9.2, so somewhat dated), and the fglrx proprietary driver.
    I don't know what would possibly happen with the latest Linux sources.
    I looked at the stuff in http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;h=0e6c3a31d3448a820f4f8a95d8f43d6d6d2a9915;hb=1e4c85f97fe26fbd70da12148b3992c0e00361fd;f=drivers/char/agp/amd64-agp.c,
    and it looks a lot more complicated than what we have in FreeBSD.
