v1 has Armada XP chipset which has packet accelerator HW in it that 
OpenWrt doesn't use. v2 has Armada 385 which doesn't have a packet 
accelerator, but instead has a much better CPU for forwarding packets.

So basically if you buy a v1 you'll get a third or so in forwarding 
performance over the v2 with OpenWrt. With the Linksys firmware I could 
imagine the v1 is faster than the v2. The v1 has a fan, v2 does not.
