Ok, I narrowed the problem to 2.6.20.7. There are a few net changes
http://eu.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.20.7
any suggestions?

I also have seen this avc on 2.6.20.6 during reboot

[ 2333.905944] audit(1187803699.273:271): avc:  denied  { send } for
saddr=192.168.1.70 src=48591 daddr=72.14.217.189 dest=80 netif=eth0
scontext=user_u:system_r:unconfined_t:s0
tcontext=system_u:system_r:kernel_t:s0 tclass=packet
[ 2334.420598] audit(1187803699.789:272): avc:  denied  { send } for
saddr=192.168.1.70 src=47248 daddr=66.249.91.18 dest=80 netif=eth0
scontext=user_u:system_r:unconfined_t:s0
tcontext=system_u:system_r:kernel_t:s0 tclass=packet

so the roots of the problem may lie between 2.6.20.4 and 2.6.20.6
