I did try renaming boot.conf to boot.conf.bak so that no modules would 
load.  Did get the same results, i.e., fatal trap, with the 
module_lookupbyname being the culprit.  Oddly enough, after I restored 
my boot.conf to its proper name, and on the next boot, I escaped to the 
boot prompt, and did a

unload
boot

all the modules would load, and my system would boot, but I'd keep getting

kernel: cbb1: CardBus card activation failed

So, I suspect the module_lookupbyname has something to do with the 
cardbus code clashing with the latest pci commits.  BTW, each time I got 
the "CardBus card activation failed" messages, the system would halt for 
half a second or so and then resume normally.  Strangely enough, the 
cardbus seems to be initializing properly.  There are no PCMCIA cards at 
all inserted.
