It gets better. I just created a footprint with some pins on mm grid and others on inch grid. I laid out most of the footprint on the mm grid (well, 0.5mm), then switched to 0.1" grid to lay out the pins. I selected all those pins, switched back to mm grid, pin-snapped to select one of them, then moved that pin onto the mm grid so it (and thus the other 0.1" pins) lined up with the other pins correctly. I still need to add mm support to the route styles dialog in the lesstif hid, though. The other ones switch according to the grid setting, that one doesn't.
