Comment 8 for bug 522318

I've got a lenovo X61 tablet, and 'udevadm info --export-db' shows WAC only for some acpi device. 'cat /sys/class/tty/ttyS1/device/id' shows WACf004 though, but since udev doesn't seem to know about the device, it isn't initialized though I have the new server and edited rules.
