I've seen something similar with...of all things...Nintendo Wii's.
When they're suspended but have 'connect24' enabled, they seem to
reconfirm network attachment with a DHCPREQUEST inbetween brief sleep
cycles (7-20 minutes).

My intuition would be to see if the client is having its interface
state cycled rapidly like that; many clients will attempt a request
to confirm they haven't changed networks.
