Certainly. Looking at there code more deeply, most of it rely on the /proc
architecture. I proposed them to move there code from outside the kernel
and define a /dev interface we could be compatible with. /dev is the best
solution I think since it could be shared with *BSD.

Moreover, a /dev interface with ioctls would be really simple... with smb(4)
as a start point. /usr/include/machine/smb.h defines ioctls, but we'll
have to handle timing constraints too.

A PIIX4 driver is available at http://www.freebsd.org/~nsouch/iicbus.html

You may try it with smb(4) if you have the hardware.
