Having 1GB as at least an option would be nice. Too many other ARM 
devices are crippled with only 128MB or 256 MB of RAM.

What interface on the A10 would this gigabit backbone be attached?

Why not just use SD flash? Something embedded would only need SD and 
RAM. Tablets use an onboard flash drive since they experience being 
dropped and are handled roughly. A blade rarely experiences this 
physical activity. Servers or a desktop would use a SATA drive.

BTW, will these boards use u-boot or some proprietary firmware for init 
and bootloader?
