KB mentioned in IRC that I should speak up:
Incident to comercial work, we have solved centos (RHEL) issues on Power5 and 390 hardware sufficient to run one of our products. It is not a full distribution rebuild, nor indeed, not even a selfhosting bootstrap set (that is on ym wish list, but ...)
390 trailhead: http://www.zSeriesPenguins.ihost.com
one gets a 90 day slice access of a box holding RHEL 4.4 with no archive access
The Chiphopper program get access to power 5, and more

z server and p server
the chiphopper folks are really helpful
mention my name, etc -- ask me if you need help or get stuck
