VoodooPS2 Interop

[1Revenger1]

There currently exists a couple issues:

• We depend on VoodooPS2Synaptics appearing in 7 seconds currently (this does not always happen on systems with PS2 muxes)
• We depend on VoodooPS2 being done waking from sleep before we do our stuff (exacerbated by VoodooPS2Mouse having a 1 second long sleep delay in it)

We currently rely on timeouts which is fine but I'd rather not need to tweak values at all. A better idea is to probably have VoodooPS2:

• Announce when VoodooPS2Synaptics detects an SMBus device, and have VoodooSMBus publish a nub then
• Announce when done waking from sleep, so that VoodooRMI knows to start doing it's thing.
