Now I have some results.

Building a custom x11 image on a 32 bit Ubuntu 10.10/psyco-dist  took 91 
minutes.
Building the same image on a 64 bit Ubuntu 11.04 without psyco-dist took 
109 minutes
(The last machine was an i7-920 w 4 GB RAM)
The first might be the same, alternatively it was a machine with 6 GB RAM.

= It takes 20% more time on a 64 bit O/S.
