Well, having some minor success using these beta drivers, at least Windows doesn't totally stop the drivers from loading (Due to "incompatibility/stability" issues), but now every time the driver loads windows tells me I need to reboot, which I do, but the process just repeats (driver install, windows wants reboot, after that driver installs).
Not sure what else to do here, but at least it's progress!
Also, just discovered the "debugging" thread. My PID as displayed by the properties window is
USB\VID_17E9&PID_02A9&REV_0123
Driver Node Strong Name: oem8.inf
