Finally got the thing compiled, and I can now load/unload the
module too -- bug fixed, thanks very much.

Unfortunately, when loaded, it spawns a kenvctrld which eats up
almost 100% of one the CPUs, so unusable at present. But I've
seen a report on the Ubuntu sparc lists with a (1 line) fix for
this problem, so I'll have a crack at that now.  

Thanks Jurji!
