performance tip: turn on agp (or, zovirl is dumb)

[Mark Ivey]

Ok, so several weeks after I asked for performance tips I wondered why
the recently posted "dmesg | grep 'AGP Aperture'" command wasn't doing
anything.  I found out that agpgart wasn't loaded, and it is apparently
pretty important.  'cat /proc/driver/nvidia/agp/status' said AGP was
disabled.  Hmm, that might cause a performance hit... :)

I had to do 'insmod agpgart' to turn it on.  Probably a FAQ by now, but
maybe this will help someone else out...
