 Yes Luke has a list somewhere for devs who want early access on his site. 

 Correct. I'm going to save you the time to search the vast archive of
 the arm-netbook mailing list:

Thank you very much!

 Subject: [Arm-netbook] Mainlining the EOMA68-A20

 i'm just talking to my host, here in taiwan, to use his equipment to
 get 50 boards made up.  i'll also get some RS232-UARTs and some
 micro-desktops made as well... or perhaps some breakout boards and the
 OTG-Host cables, have to see.

 any takers please put alias down here so i get a quick idea of numbers

This looks very promising. I need to ask a couple more questions:

Could parabola as a whole go into that list, with a to-be-determined
number of cards, or would we need to name the individual hackers?

We have at least three people working on the arm port, maybe more. Would
asking for ~5 cards still be in the right ballpark?

Would the prototypes be lent to us? donated? sold?

Is there an ETA?

Best,
