Has anyone ported RTEMS to the 68060 yet?

I am using the 68060.

I decided against the emulation path for performance reasons. I do not 
need to support code with these instruction, for example a 68040 binary.

I built GCC/newlib and RTEMS for the 68060. The compiler will not 
generate the instructions fpsp needs if the -m68060 command line switch 
is used. I remeber a multilib patch heading into gcc not long ago that 
made the 68060 a separate variant. I have a patch for the older gcc

I am using the MVME172 at the moment. The i82586 network driver is in 
libchip but it needs a patch from me to work. (Joel, I not forgotten :-)).
