5 days later, I've finally processed all the vbios I received (more than 
300 mails, 275 vbios in the end).

I first received a bit more than 80 mails because of phoronix 
(http://www.phoronix.com/scan.php?page=news_item&px=ODY2Nw and 
<http://www.phoronix.com/scan.php?page=news_item&px=ODY3Mw>) and then, I 
received a lot, lot, lot more all of a sudden. It happens that a Russian 
linux website has relayed the call 
I would like to thank them both for relaying my little call, I wasn't 
expecting such a big response!

I created a private git repository to store them all and make them 
accessible to some devs. If anyone has a problem with that, please let 
me know.

Also, with almost 300 vbios in the database, I thought it would be cool 
to make some stats on the userbase who answered to our call.
The diagrams speak for themselves. You'll find them enclosed in a pdf 
(for the diagrams), a csv (for raw data) or an ods (for both).

Thanks again to all of you who sent the information on your card!
