Chris's dmesg show 32MB of memory, in the range we know causes trouble.

I thought that I had them working, i386/include/mpapic.h, i386/i386/mpapic.c:
int	apicIPI();
int	selectedProcsIPI();
int	allProcsIPI();
int	allButSelfIPI();
int	selfIPI();

If these aren't adequate and/or usable let me know and I'll get you what you
need ASAP!
