I'm not sure what you're seeing is really a kernel bug (unless you don't ship the latest OLPC kernel). It works fine for me even across several hundred suspend/resume cycles (it gets woken about once per 1-2 minutes by IGMP queries from the AP), though this is with an otherwise unused WLAN, so rekeyings are infrequent. And rekeyings might be exactly what's causing you trouble: According to Dan Williams, the libertas chip doesn't wake us for these [1]. I haven't had time to verify that yet. Upgrading to the latest NetworkManager version might also improve things a lot.
