The glint driver supports overlay on appropriate 3Dlabs cards
(Oxygen VX1-1600SW is the only one I tried, and it works).
*Some* S3 cards have suitable hardware (TVP3026 or RGB526 ramdacs,
possibly other members of those chip families); I don't think that
the drivers support the feature yet.

xinerama only exports features available on all screens, so you would
lose overlay in this case.
