dmesg just reads the kernel buffer, but you are correct that pci conf
does read this info..  Why don't you read the source for pciconf?  If
you installed the source, it's availabe in /usr/src/usr.sbin/pciconf?

Or you can read it on the web at:
https://svnweb.freebsd.org/base/head/usr.sbin/pciconf/
