Ben:

I have a driver for 2.4.x that works with our SFP/XFPs.  We also have a 
bunch of other 'stuff'
hanging off of muxes.  I haven't given it a go on 2.6, but I have it 
compiled and it doesn't complain on
startup.

Not sure if I should send it here, as it won't be in patch form...

Lemme know if you want a look-see,

Travis
