	I'm surprised that you had to actually dig into the code
	to figure this out.  (Altho lots of times reading tthe source
	is drastically easier than wading thru obscure man pages:
	*sigh*)

	Hm.  Just checked NOTES; ISA, eh?  well, you said this was
	a strange one.

	Two questions if you're still at-keyboard at 17:30-18:00.
	First, is there a way to unload the csa *.ko via cmdline?
	Second, where should this be posted?  I'll add things to
	the FBSD laptop site in the 600E section;  but anywhere
	else?

	Got it.

	Will do, Kevin.  tia, of course.  I owe you one; maybe a couple:)
