Did it hurt? ;-)
Is this with full-on Acrobat, or just the reader? Have you tried any of those "clean up adobe" third-party things that make it not load all those plug-ins? Have you tried any third-party PDF readers?
I've got Adobe reader, and I'm pretty sure I ran one of those "get rid of the plugins" things, but it's been so long I can't remember, but I've _never_ had adobe reader crash the system.
Another thing that might go in my favor is that having a dual-boot system (W2K and Slackware 11.0), I've got it configured so that when I boot W2K, I don't even connect to the network. Is Adobe trying to phone home?
Good Luck! Rich
