These messages were just not present in 6.0, and they are only enabled
in 6.2 and later if bootverbose is enabled (i.e. boot -v).  Your system
is 6.2-PRERELEASE, so upgrading to the latest RELENG_6_2 should quiet these

In your machine's case, the I/O port accesses are simply PCI config reads
and writes.  It's really a buggy BIOS since ACPI provides direct methods
for accessing PCI config space which the BIOS should be using instead of
doing it "by hand" by banging on the I/O ports directly.
