Default Re: DK8N, 6800GT & 4GB mem

WOW, I'm not sure what the **** happened, but I just did a
Code:
modprobe agpgart
modprobe amd64-agp
and it worked! Although I'm on an ssh from work right now, and I can't verify that the X server doesn't crash until I get home, but this is now at the end of my dmesg output:

Code:
Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected AGP bridge 0
agpgart: Setting up Nforce3 AGP.
agpgart: Maximum main memory to use for agp memory: 2830M
agpgart: AGP aperture is 256M @ 0xc0000000
it has NEVER been successful loading before! MAN I hope it's working. But I hate those "it just started working" problems, because you never know what was wrong, or when you'll see it again.

Well, it looks like I got too excited too soon. I just re-started X (remotely) and now I have this in my dmesg:

Code:
mtrr: type mismatch for c0000000,10000000 old: uncachable new: write-combining
NVRM: AGPGART: unable to set MTRR write-combining
NVRM: not using NVAGP, AGPGART is loaded!!
mtrr: type mismatch for c0000000,10000000 old: uncachable new: write-combining
NVRM: AGPGART: unable to set MTRR write-combining
NVRM: not using NVAGP, AGPGART is loaded!!
This is with NvAGP set to 3. I feel like I'm getting closer, though.

Update: one more thing that might be useful:

Code:
darkstar:~# cat /proc/mtrr
reg00: base=0xba000000 (2976MB), size=  32MB: uncachable, count=1
reg01: base=0xbc000000 (3008MB), size=  64MB: uncachable, count=1
reg02: base=0xc0000000 (3072MB), size=1024MB: uncachable, count=1
reg03: base=0x00000000 (   0MB), size=4096MB: write-back, count=1
