Linux as bring-up

I feel I'm too close to the project to be able to comment independently ... but the comment
about Microsoft Windows at least reminds me that Linux has been used for the XO as initial
bring-up and design validation.  Which seems to happen more and more these days.  On the other
hand, the initial bring-up of hardware was often Mitch Bradley and the FORTH based
OpenFirmware.  I wasn't there, but I was eagerly listening on IRC.
