Between Freescale's mail server and the trouble we're having 
with Google right now (along with thousands of others), I am 
NOT surprised it got lost somewhere along the way.

I wasn't bitching :)

Okay, non-trivial was pretty much what I was looking for, I 
was just trying to weigh up how much effort is required..

If you actually scope it out in any detail or someone has some 
10% time and decides this would be an awesome project, give me 
a nudge? My MPC8641D is itching to actually do something 
besides build packages. Actually having 8GB of memory would 
REALLY help run SUSE Build Service :]
