Does it actually not work, or does it just complain about it?  I know
lots of router/switch vendors will complain, but the optics still
actually work just fine.

I know the Intel ixgbe driver won't actually turn on unsupported SFPs by
default (which is annoying), but there's an option for the module to
turn them on, allow_unsupported_sfp (and then they work fine, including
"ethtool -m" to see DOM info).  I don't know if there's a similar option
for Broadcom.

Sigh, games vendors play with standard ports...
