Added the CMD640 (but the associated PB520R is not yet properly done, needs the 82091AA, so it's disabled until I implement it), fixed initialization of the IDE registers on the SMSC southbridge, bumped up the number of emulated serial ports to 4 (was 2), and added the ability to properly have multiple W83977's on a single machine.
