you'll also need to recompile the kernel
 Actually, I don't think you need to re-compile anything, just link in 
 m40.o
  instead of m45.o; I think all the C code checks for
'cputyp == 40' or
 whatever, as the case may be.

If I get farther with an EIS, if possible can you help me to link in m40.o
instead of m45.o?
