Does it work if you statically assign the IP's? (rule out dhclient)

Are these using a nic -> usb device?

udev maybe the culprit? Although I did notice with the 2.6.40 kernel  
on x86 (yeah i know. x86 blah..) you needed something like the onboot,  
nm_controlled, uuid or type in the ifcfg-eth0 file (i forgot exactly  
which.) in order to get it to plumb the device when you activated it  
with ifup eth0.
