Actually, the BP6 supports AGP 1X and 2X.
The BP6, as we all know, runs on the BX440 chipset. AGP 1x is defined as running at 66MHz, and having a dedicated path from the chipset. AGP 2x runs at 133MHz, and likewise, 4x and 8x run at 266MHz and 533MHz, respectively. I've pored over the BX440 specs and google my brains out trying to find a definitive answer on what AGP speeds the BX440 actually runs at, not just supports. The Intel docs just say "supports AGP" as if written before AGP 2x.
The BIOS on the BP6 has only two settings for the AGP clock, 1/1 and 2/3, presumably for use with the 66MHz FSB and the 100MHz FSB, respectively. Which means, our beloved BP6 has a 1x AGP port only. It
supports 2x cards, they just run at half bandwidth. It also supports 4x Universal cards, but they run at quarter bandwidth.
The cards themselves still run at full speed--the clock speeds on a video card are independent of the AGP bus from what I've seen. The AGP bus speed just determines how fast data can run between the CPUs, chipset, RAM and video card. So, if you have a 2x card and you're running at 100MHz FSB, switch that AGP/FSB ratio to 1/1 to overclock your port and get AGP "1.5x." It's as fast as the board will go, normally.
The only way to get any more speed out of your AGP port is to overclock the BX440. It is not an easy path, and it is not even gauranteed to work. I've seen screenshots of a BP6 POSTing at 124 and 133 MHz FSB, but I do not know what the AGP multiplier was set to. Theoretically, if you set the AGP/FSB clock to 1/1 and overclocked the BX440 to 133MHz, you'd have an AGP 2x port, but again, I've only seen screenshots of a BIOS POSTing at these speeds. I get a big nothing on my board right now when I try to run at 124 or 133. (This is my other reason for insisting on trying to get my BP6 to go all the way, I want that bandwidth to the AGP port).

If you really want faster GFX performance, then you'll need a newer motherboard and CPU.
Sorry if that's a little disappointing.

Alas, I have to agree with this one. Unless there is some new feature that you want and not more speed, you need more bandwidth to the video card, and that just means a new motherboard and processor. A dual PIII system probably won't set you back too far, and the power consumption is still reasonable. For that matter, Athlon MP's will run hot, but they aren't unreasonably priced (as for me, I'm never running a single processor system again--when I started using my BP6, I touched fire, and don't want to let go).
