Applications can allocate arbitrary amounts of buffers that are
dynamically bound to the GPU.  The limit of what can be bound at for a
single draw call is defined by the hardware, so there are no user
controls.  The only information you get on that limit is:

dmesg | grep agp:
[    2.283526] agpgart-intel 0000:00:00.0: detected gtt size: 2097152K total, 262144K mappable

so this system can map 2GB at once.
