Default Should I blacklist ati_agp module?

I have a Biostar graphics card with the Geforce 7300 LE GPU and am trying to figure out how to take advantage of its MPEG-2 decoding. I've noticed that the CPU usage in mythfrontend is actually a little higher when my XvMCConfig file contains libXvMCNVIDIA_dynamic.so.1 than when it contains the original libXvMC.so.1. I have configured mythfrontend to use "Standard XvMC" for MPEG-2 decoding. My xorg.conf is attached.

I'm guessing I need to do a little more tweaking. I plan on enabling "UseEvents", but I'm also wondering if I need to set "NVAGP" to 1 and blacklist ati_agp.

Chapter 12, Configuring AGP, mentions several different AGP chipsets that are supported by nVidia's AGP driver, but I can't tell if it applies to my hardware. I do know that, according to lsmod, both nvidia and ati_agp depend on the agpgart module. I also know that my motherboard (ECS RS482-M754) has an Integrated ATI Radeon Xpress 200. What I can't seem to find, either from ATI/AMD's website or from the ECS RS482-M754 documentation or from dmesg, is whether that means the motherboard or integrated graphics have a chipset supported by the nVidia driver.

So, I'm hoping you can tell me whether setting NVAGP and blacklisting ati_agp is going to help or hurt me? If you can suggest other tweaks that I might be overlooking, I would welcome them, too.

FWIW, here's info from /proc/driver/nvidia:


NVRM version: NVIDIA UNIX x86 Kernel Module 100.14.19 Wed Sep 12 14:12:24 PDT 2007
GCC version: gcc version 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)

Model: GeForce 7300 LE
IRQ: 20
Video BIOS:
Card Type: PCI-E
DMA Size: 39 bits
DMA Mask: 0x7fffffffff
Bus Location: 01.00.0
Thanks in advance...
