Below is the commit, it needed a small amount of massaging to apply the 
void * -> unsigned long * change in the x86/bitops topic.
        

Well, that's your bug right there.

The macros very much depended on the pointers being "void *", due to 
the pointer arithmetic (which is a gcc extension that we use 
extensively - "void *" arithmetic works as if it was a byte 
pointer).
      

duh, yeah - of course. Will retry with that fixed :)
    

yep, the patch below got it all going and it passed 5 hours of testing 
already. Thanks,
