ACPI code hasn't been touched since then, so I guess that the
following discussion also applies to you since you're using xl(4) driver:

  http://leaf.dragonflybsd.org/mailarchive/commits/2005-01/msg00325.html


Please try backing out the commits:
# cvsweb="http://www.dragonflybsd.org/cvsweb/src"
# fetch -q -o - \
        "$cvsweb/sys/bus/pci/pci_if.m.diff?r1=1.4&r2=1.5&f=u" \
        "$cvsweb/sys/bus/pci/pci_pcib.c.diff?r1=1.3&r2=1.4&f=u" > ~/pcib.diff
# patch -d /usr/src -R -p1 < ~/pcib.diff

and rebuild your kernel and see if it's fixed.
