'lspci' question

[flyinggreg]

I am trying to get better performance on a desktop with Jaunty so I can run Flightgear. It's a 2.8GHz, 768Mb DDR with a 82845G/GL/GE video processor.

I have read the issues with Intel video drivers with xorg and have been trying to get the frame rates up (>3 fps) in Flightgear - they are ~14-16 fps on penguin racer.

So...I have been looking at the 'lspci -vvnn' dump and was wondering if xorg is getting confused (or am I confused). Here's the part I have a question about:

The question I have, does it appear there is 2 occurrences for the same video processor but using different memory allocations and drivers???? To me it appears there is 1 occurrence for an allocation of 256-Mb (which I set in BIOS), and another for 128-Mb. I reading this correct?????

I am thinking this might have to do with my LOW fps in Flightgear.
