Since no one is bothering to deal with this mailing list any more, and
the driver no longer works with the kernels of the current version of
most mainline distributions, I presume it is now effectively defunct.
It really shows the dangers of relying on proprietary code in linux

I have a patch which I use to compile the hsf driver with the latest
kernels, which I attach (I don't know if the mailing list will strip it
off, it might).  I do not guarantee it, because none of us see the
proprietary code which it interfaces with.  In particular, the file
osservices.c uses the global kernel lock for a purpose which is not
obvious to me.  I have replaced it with a local lock which may well
either not meet the original purpose of using the global lock or may
now be completely unnecessary.
