You could try the patch "singleroot.3.patch" found at
http://trac.openlayers.org/ticket/1666 (patch is against trunk). An
example is online at
http://dev.openlayers.org/sandbox/ahocevar/singleroot/openlayers/examples/select-feature-multilayer.html

This uses a different approach: you have one SelectFeature control,
and configure it with an array of layers instead of one layer. The
events (e.g. featureselected) will still fire on the separate layers.

If you decide to use that, please report how it works for you by
commenting on the ticket.

Regards,
Andreas.
