Understood, but in practice I don't think the 10K or so matters that
much on a typical 85xx board, and if the user really needs to trim
things down, they always have the option of manually ripping the phy
stuff out.

It exists in a few places, but it's not that common, and often it's 
obvious what went wrong when the module won't load because some kernel 
hook didn't get built.  It's not a huge deal, but I'd rather avoid 
introducing another instance.
