I talked about machine detection a while back.  My idea is following:

0. all machines that are *configured* into the image will supply <my>_detect()
and <my>_setup() functions.

1. at MIPS start up, we loop through all <my>_detect(), which returns three
values, a) run-time detection negative, b) run-time detection positive, and c)
no run-time detection code, but I return positive because I am configured in.

2. the startup code resolves conflicts (which sometimes may panic); and decide
on one machine.

3. then the startup code calls the right <my>_setup() code which will set up
the mach_type and other stuff. 

 It sounds reasonable.  We may also check the Alpha port for solutions --
it supports multiple dissimilar systems as well.
