Speaking of which, has anyone found a good way of dealing with those
thermally enhanced packages where they sink the lead frame to a pad
underneath the chip?

By hand I assume..

Put a PTH in the underside pad, make it just big enough to get a fine
iron tip through. Solder the outside pins as normal (tag down the
corners, little bit of solder on tip, draw across pins- finicky with
little short pins but works) then flood the underside from underneath.
