I'm at home now ona box with yaird man yaird says that it will exclude modules listed in /etc/hotplug/blacklist and in /etc/hotplug/blacklist.d but I don't know how that plays with purging hotplug for the udev upgrade. regardless, though, putting usbhid in one of those places would cause yaird to NOT include that module in the initrd... at least that's how I read the man page.
