If you load the puc(4) driver as a kernel module (puc.ko), you should
load the sio(4) driver as well. i.e.:

sio(4)		puc(4)		work?	
--------------------------------------------------
builtin		builtin		OK
builtin		module		NG
module		module		OK
module		builtin		Maybe OK
--------------------------------------------------
(builtin = kernel builtin, module = kernel module)
