I suspect the answer is to use OpenGL. Take a look at this note about fast OpenGL texture uploads:

http://developer.apple.com/samplecode/Sample_Code/Graphics_3D/OpenGLFastTexDemo.
htm

which ends with the text:

"With all 3 of these options correctly managed, what you get is async AGP/PCI DMA transfers straight from your memory to texture memory. Meaning that the driver never touches the pixels with the CPU."
