After much searching, I finally found a message from Marcel Moolenaar to
freebsd-stable date 2008-05-06 regarding PCI serial cards working in 6.2
but not 6.3. The issue (and mine) were due to a problem with v1.51.2.3
of sys/dev/puc/pucdata.c and caused by the commit to add support for the
six-port version of my card. The following change:
--- pucdata.c.orig 2006-12-15 14:31:37.000000000 -0800
+++ pucdata.c 2008-11-16 15:34:50.000000000 -0800

Fixes the issue and I now have:
