System: NetBSD 1.5X NetBSD 1.5X (GED) #0: Sat Sep 15 20:51:52 CDT 2001 i386

Machine: i386
	dd if=/dev/cd0a of=temp.iso
	produces a file 4x the size of a CD-ROM image, which has oddly
	repetitive patterns.
	See above.
	I am assuming the kernel is confused in some way by the raw device
	having a block size other than 512?
