	Ok, to whom it may concern : I originated the current code to 
read the PRAM (including access to all the goodies stored there, not just 
the time).  It's definitely broken on anything I haven't tested it on - 
tested hardware right now consists of a Mac IIx.  That doesn't mean 
that it doesn't work, that just doesn't mean that it does work.  So 
what ?   Well, two things.
	One - if your kernel displays PRAM time and MacOS time (as in the 
example above) and the two don't agree to within about ten minutes, then 
send me personal mail with make and model number, and the numbers printed 
out, if at all possible.  DON'T copy it to the list.  Armed with this 
information I'll see what I can cobble together to fix the problem.
	Two - I haven't a clue as to the cause of the FPU error - my code 
doesn't access that capability.  So, if you see that error, it has 
nothing to do with the PRAM routines.  If you see that error, and the 
PRAM time inconsistancy warning, and then you recompile and BOTH errors go 
away, then it's really probably Allen's game, but send me mail with the 
specifics and I'll confer with Allen to get the problem fixed.  No 
guarantees, no promises, no time frames - remember, I'm NOT running for 
elected office.
