/*
	note:
	moved DMA acceleration 'top-level' routines to be integrated in the engine:
	it is costly to call the engine for every single function within a loop!
	(measured with BeRoMeter 1.2.6: upto 15% speed increase on all CPU's.)
	Leaving PIO acceleration as it is for now, for the purpose of benchmarking :-)

	note also:
	attempting DMA on NV40 and higher because without it I can't get them going ATM.
	Maybe later we can forget about PIO mode acceleration totally (depends on 3D
	acceleration attempts).
