Interesting coincidence - this week's edition of the kernel page on 
lwn.net has a discussion about using -Os to build the kernel.  It seems 
that there is simply no downside to doing this and one wonder why it isn't 
the default.

Yes the driver is built outside of the kernel, but I had been presuming 
that it should be hooking up with whatever configuration was used to build 
the kernel - config settings, header files, and compilation flags.  That 
would only seem to make sense.  However you raise a good point and I'll 
look into it.
