I'd like to see a comment (with PR# if appropriate) explaining clearly
*why* it isn't enabled for <ARMv6 even with a bleeding-edge compiler.

Russell's test also seemed to indicate that the 32-bit and 64-bit swap
support was present and functional in GCC 4.5.4 (as indeed it should
have been since 4.4), so I'm still not quite sure why you require 4.6
for that.
