	Here is probably more info than needed, but there may be some
relevance. I couldn't exactly understand how you represented the barcode, so
I went with a visual type description...

Serial #16777215 (I thought I saw something about this having some relation
to the hostid...)
1) four-character code: AUSY (yellow)
2) barcode: 
-  = space
-- = double space
1  = single width bar
2  = double width bar

4) hostid: ffffffff
barcode sticker on top, powersupply edge: 5011382051207

- Maybe these have some hint?
