Has anyone gotten NAP/DFS to reliably work on a 7448?

I'm seeing strange problems with peripherals...(using a ram disk

Could it be that your host bridge isn't properly waking up the CPU to

some cases, I know Apple had workarounds in those areas, maybe something
along those lines need to be configured in the chipset).
