  No, not impossible.  Sun puts the ethernet address in NVRAM on the 
system board, and it is used by default for all ethernet interfaces.  It 
is assumed that if you have multiple ethernet interfaces, they will be on 
separate segements.  Basically, this design is for netbooting purposes, 
as you can set boot options (kernel, etc) per machine, rather than per 
interface.
