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