glx / i915 / nvidia

i seem to be experiencing a glx problem with breezy.
my computer is a shuttle 61G2 with integrated i915. previously i was
using mandrake 9.2 and glx performance was great. as an arbitrary
visual metric, glxgears would simply fly.
*please give me the name/usage of an ubuntu command if precise fps would
help
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
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?
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.
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?
and... just because im wondering... how the heck does a pretty old
version of mandrake have great i915 driver that breezy fails to include?
xorg.conf with nvidia card. i use only one card at a time. when i
change i modify the following:
Driver "nvidia" -> i810
BusID "PCI:1:0:0" -> 0:2:0
