AGP-Aperture means a special paging circuit in the mainboard(!) chipset
that maps pages of memory into a linear PCI bus memory window.
The more precise term for the system is GART and its a subset
of the AGP specification which also specifies the AGP transfer modes.
Enter your bios and tune your APERTURE SIZE e.g. to 8, 16, 32 or 64 MB.
It does not hurt if its too big unless you really allocate the space
because it must be backed up by existing main memory. A bit bigger than
needed by your applications texture demand is okay because this will
avoid fragementation of that page rempaping range. Yes, even the gart
range memory pool can be used up.
Aperture size and grafics memory size are not related in any way.

I would assume 200 FPS is software rendering,
but 480 FPS looks more like hardware rendering. (hmm, or a pretty fast CPU)
Can you check with glxinfo if Mesa or hardware rendering is running?
Check also with "/sbin/lsmod" if respective kernel modules are active
and countercheck in XF86 logfiles if kernel modules init did succeed.
Possilby the most recent "beta" drivers from the CVS repository
might give you much better numbers, but i am not really sure about it.
I just dont have a URL handy for you for this resource.

Plese if you do repley the do it to the dri-devel list
so the most expirienced person in your specific subject
will be able to answer the questing. Thanks.
