Hrm, dirty handling is kind of interesting. It is unconditionally set in the write function and never cleared so we'll always rewrite a register if it's ever been touched. Is it worth remembering the default values and just comparing with them, the memory overhead will probably be low since we only have one bitfield value here... (and remember that we'll be unlikely to allocate memory in 21 byte packed hunks with no overhead...).
BTW, this does look like a very nice win overall.
