Unfortunately the latest fedora 16 kernel, 3.1.6-1.fc16.x86_64, renders this fix ineffective and again cannot resume wifi after a sleep and must reboot. Therefore must stay with older kernels for this to work and for wifi to resume after sleep: 3.1.5-6.fc16 is still OK with bt_coex_active=0 3.1.5-2.fc16 is also still OK with this fix.
