Just a couple more data points. I have two machines, an elderly K6-2 
running at 400 MHz and a relatively modern P4 running at 3.4 GHz. 'make 
installworld' takes about 8 minutes on the slow machine, and just a few 
seconds on the fast one. Point being that you needn't have much downtime 
for this.

That's what I would do, but it depends on how lucky you feel. There are 
ways to get to the console without traveling to the colo.

HTH, and good luck.
