Actually, you can compile it by commenting out the offending line in 
modules/osservices.c (line 425), comprising:

  current->pgrp = 1;

The kernel struct task_struct no longer has a member pgrp.  It has a private 
member __prgp, but it seems that that is only supposed to be accessed by the 
method:

static inline pid_t process_group(struct task_struct*)

declared in linux/include/linux/sched.h.  As that obtains __pgrp by value and 
not by reference (it is effectively read only) I assume therefore that the OS 
will control its value (but I cannot say for sure).  Anyway, commenting out 
the line mentioned above appears to work with the free version of the HSF 
driver, and I would be interested if it works in the paid-for one if you are 
using it.  I am even more interested in the upgrade policy as I haven't yet 
bought the driver, and I won't do so unless I know it works correctly.

I have not tried to see if the driver works with the mm patches.  It may or 
may not.  That is one of the several problems with binary only drivers.

Chris.
