Hmm... Is this due to a spec definition, or is it just how satellite
operators decided?

If ARIB spec doesn't allow polarization set, we should remove it from the
Kernel DocBook. 

Btw, how does the PT1 driver handle those parameters? If it just uses
frequency (it seems so), then the only valid parameters for ISDB-S are
	DTV_FREQUENCY
and
	DTV_STREAM_ID

(and, eventually, polarization, if ARIB spec allows it)

right?

Could you please send us a patch fixing it at the Kernel DocBook:
	Documentation/DocBook/media/dvb/dvbproperty.xml

Thanks!
Mauro
