A few questions about integrated graphics

I have a good understanding of how some software can be written and
optimized to perform better in a 64-bit OS.
(http://www.agner.org/optimize/). I understand the relationships
between CPU speed and cache sizes, system bus speed and RAM timings.
I have a few questions regarding Intel integrated GPUs and graphic
performance in Linux:
1. Are there any benefits to using a 64-bit kernel with integrated
2. Will Intel GPUs benefit much from faster bus speeds and faster ram
timings; much like the CPU (i.e: is what's good for the CPU also good
for the GPU?)
3. Do Intel GPUs have the equivalent of a cache?
4. Any mesa/intel xorg driver code "optimized" for 64-bit, CPU cache
size, multiple cores, etc...?
5. Some software (I think mplayer is one and most certainly ATLAS)
ignore your compiler settings and create optimized code automagically.
Anything I can do when compiling xorg/intel/mesa drivers to improve the
Thanks for entertaining my curiosity. The net is littered with accounts
of persons spending all their time building/optimizing their
hardware/software and the only definitive statement they make is that
the result "felt snappier". Rather than suffer a placebo effect I
thought I'd just ask those who my actually know.
