John,
Thanks for the insight.  Not only can i provide a verbose dmesg, but I
can do so for both the beta and for HEAD

prolepsis# uname -a
FreeBSD prolepsis.math.uiuc.edu 7.0-CURRENT FreeBSD 7.0-CURRENT #4:
Fri Jul 22 23:53:40 UTC 2005    
kaduk_at_prolepsis.math.uiuc.edu:/usr/obj/usr/src/sys/PROLEPSIS  i386

as well as a regular dmesg from HEAD, since there are even more
curiousities, namely, in the verbose boots, pci_link1 is assigned an
IRQ,
but apparently not in the regular boots.

I hope the attached dmesgs are meaningful,
