Use up to 256 separate vertex buffers
This allows us to only call i830WaitSync once every 128 calls to composite
rather than on every call. However, we do need to also call MI_FLUSH to
avoid the vertex cache getting in our way, (since our "separate" buffers
are all allocated as one contiguous chunk).
