"I don't know", and I'm afraid that's the best you'll get.

OpenVPN "--dev tap" will usually bridge Ethernet traffic around just fine
(for example on linux, bridge "tap0" and "eth0" together via brctl), but
I'm not sure how Linux in general and OpeNVPN in particular will deal
with odd ethertypes.

IPSEC & friends and anything that is "layer 3" will not handle this.

Linux has (or had?) "gretap" tunnels, which basically also does remote
ethernet, only over GRE not over OpenVPN, and then you can hook said
gretap intreface into a bridge.  This would take OpenVPN out of the 
equation (in case OpenVPN is refusing cooperation), but still relies
on linux + bridge handling unusal ethertypes correctly.

Keep us informed! :-)
