Not so - they do exactly what the Ollicom guy is talking about but done
cleanly. There is no GPL code in their driver nor claim to be. Bits of
their driver are binary only so if it breaks or they get bored of supporting
it you lose. They do give you source to some bits however.
In their case its really odd cos they ages ago used to give out the source
to their LynxOS and other driver bits so reconstructing their magic binary
only files is ridiculously easy
