I'm using a P4 Prescott and an Intel Montara 852 chipset. I ran AIDA32 and got the following info.
Chipset Properties:
Motherboard Chipset Intel Montara-PM i852PM
In-Order Queue Depth 12
CAS Latency 2.5T
RAS To CAS Delay 3T
RAS Precharge 3T
RAS Active Time 7T

Integrated Graphics Controller:
Graphics Controller Type Intel Extreme Graphics 2
Graphics Controller Status Disabled

Does anybody know how to enable Intel Extreme Graphics 2?

I tried downloading a graphics driver from here.

but I got an installation error after downloading from both sources, it said files missing. I'm dual booting Tiger and XP, I installed using Generic Install DVD release 1. Dell Inspiron 5160. I figure that by enabling the intel thing, I might be able to get quartz extreme and core image to work both of which are disabled according to the system profiler.

These aren't drivers for OSX86, it will not work.
At this time only the i915G is fully supported
