Change it to CFLAGS="-mtune=pentium4" & `emerge -e world`; this will  
recompile your binaries so that they'll work on any PC processor.  
After you've booted with the new processor you can re-optimise for  
that. --funroll-loops FTW!

It's only the CHOST that can really stuff you up - I don't think you  
should be changing this on an installed system, and I think you'll  
have never changed it.

 From my make.conf.example:
   # ...All modern systems
   # (even Athlons) should use "i686-pc-linux-gnu".

I don't _think_ the kernel is compiled with the optimisations in  
make.conf, but even so it doesn't take long to compile a new kernel &  
boot with it before you migrate to the new system.

For WAF [1] make sure an ssh server is in your default runlevel and  
shell in to set these tasks running just before you go to bed at  
night or when you're at work. Use `screen` so you don't have to stay  


[1] If that means what I think it does.
