Matt, you're too cool for words.  :-)

i won't blush.
   
   I just plopped this into the kernel on my SS1, and had to make one teeny 
   little addition for sunos_util.c to build -- need to include 
   <sys/exec.h>.  No biggie.
   
not entirely sure how this got through;  i had to do it just now with
a new kernel i built, but the one that is (still) running didn't.  i
did remove an include for sys/exec.h from sunos_util.h, because it was
conflicting elsewhere.  i guess my .depend was out of date  :-)
