If someone has confirmed it is good, then we can use it. But not until 
we get positive confirmation (I guess richard confirmed it?).

I'm really paranoid about this version issue. We had a big problem, 
never resolved, where somebody upgraded the epia chipset source for a 
newer epia part and just totally broke the tree for epia (the changes 
made should not have been a problem, according to everything we knew; 
they nevertheless did not work). Yes, you read that right: a fix for 
epia broke epia -- it was a chip rev. issue problem, I think. Sometimes 
it can be something as minor as a "date fab'ed" problem -- bugs and bug 
fixes sneak in to the chips, and a bug *fix* can cause as much trouble 
as a new bug.

We've never recovered from that; it does not matter, as epia is no 
longer made, but I was pretty unhappy about it. So, we definitely don't 
want to bump the version numbers without a confirmed successful build. 
As time goes by, we maybe ought to require two "success reports" for 
OLPC, to be doubly sure.
