upon installing kubuntu 5.10 glx performance went in the toilet.  my 
favorite emulator ePSXe remains unusable.

i can use either of the following:
the integrated i915          *cant figure out how to use the native 
915 drivers

or

an agp nvidia geforce 256  32mb     *installed binary driver
Wrong, if you can't find a driver for the i915 chipset, then definitely 
don't just use any random driver.
using glxinfo both report that DRI is working but both cards preform 
horribly regardless.  is it possible that mesa is still doing 
everything in sw?

no
Notes:

i would like to get my origional performance on the i915 and uninstall 
the nvidia card. but if the only way to get acceptable performace is 
to leave it in... well... you get the idea.
in moving from mandrake i went from kernel 2.4 to 2.6... any issues 
there?  dont remember which xserver i was using.

it shoudl work better in 2.6, not worse, provided you ahve the right 
drivers installed.
also, ive tried to compile the native i915 drivers but i cant find the 
deb kernel headers for 2.6.12-9-386.  can anybody point me in the 
right direction?

There aren't any. Use 2.6.11 if you want kernel headers. Alternatively 
compile the latest kernel headers and kernel from the vanilla linux 
kernel without alterations.
and... just because im wondering... how the heck does a pretty old 
version of mandrake have great i915 driver that breezy fails to include?

Something to talk to the devs about, or maybe you're doing something wrong.

Why are you using the nvidia-glx package with your intel graphics 
device? Obviously it wouldn't work. Either deactivate the intel device 
and use the nvidia one or pull out the nvidia one as superfluous. You 
should not use the nvidia drivers with a non-nvidia card.
