are you sure that the DOS filesystems know that they end at the end 
of their slice...
if you shrink a DOS partition, but don't re-format the 'drive', then dos will
happily allocate blocks in the next slice
(well what used to belong to it)
I believe 'fips' can fix that..

your fdisk and disklabels look good..
strange..

hmmm,  a C partition, and it's right after the swap too..

lp0 is a the lp port.. npx is the numeric coprocessor..
check /usr/src/sys/i386/conf/LINT

ignore the # cylinders..
what does boot -v say about BIOS geometries?
(use dmesg to see it after booting)

excellant.. unfortunatly I can't see anythong wrong there, 
unless the swap is going to the wrong BSD slice..
(hmm might this be a bug? )
(It MIGHT be untested code?)

you seem to have done a very proffessional job of partitionning your disk
I can't fault it, unless the BIOS sees things differntly..
