Change 96628 by jb at jb_freebsd2 on 2006/05/03 22:41:39

	More 'const' grief. It only takes one attempt to cast a char pointer
	to drop the 'const' to ruin an entire 'const' day. Declaring things
	'const' is only worthwhile if you're going to obey them.
	
	In FreeBSD, the default kernel module compiler options detect the
	inconsistency in Sun's code. Sigh.
