It is a typo by Apple. It is the name in the firmware of my
PowerMacG4 466 (PowerMac3,4) under the OF prompt too 
(psuedo-hid and psuedo-sound). 

OTOH in my Pismo (PowerBook3,1) these same name are spelled 
correctly, despite the fact that it is older (but it has had 
at least one firmware upgrade while the G4 has none AFAIR).

/proc/device-tree keeps the names given by OF and only adds 
a few of its own, "linux,phandle" mostly.
