297 Used a bit like CP_SET_CONSTANT on a2xx, but can write multiple
298 groups of registers. Looks like it can be used to create state
299 objects in GPU memory, and on state change only emit pointer
300 (via CP_SET_DRAW_STATE), which should be nice for reducing CPU
301 overhead:

448 Is 0x8801 a register offset?
449 This appears to be a special sort of register write packet
450 more or less, but the firmware has some special handling..
451 Seems like it intercepts/modifies certain register offsets,
452 but others are treated like a normal PKT4 reg write. I
453 guess there are some registers that the fw controls certain
454 bits.
