bug 12976: The new keyboard framework sends only raw keyboard events, it turned out that it does not work with Xen/KVM hypervisors(only VMware supports standard raw keyboard events), Xen/KVM accept only cooked keyboard events, to maintain cross hypervisor compability, US english keyboard will be handled in the new JsCookedKeyboardMapper class
