acpi: bad read from port / bad write to port

[Toomas Aas]

I cvsupped my source to RELENG_6 yesterday, built the world and kernel 
and rebooted into the new kernel in single user mode to test it out. 
Boot messages had a series of messages such as:

acpi: bad write to port 0xcf8 (32), val 0x80003884
acpi: bad read from port 0xcfc (32)

These messages do not occur with my present system, which is 6.1-STABLE 
from May 9th, 2006. Some googling seems to hint that MFC of 
src/sys/dev/acpica/Osd/OsdHardware.c as of  May 11, 2006 *may* have 
something to do with it. But I am not a developer enough to understand 
whether these messages are merely cosmetic or should something be done 
to fix them.

The machine where this is occurring is based on Chaintech 7AJA/0 
motherboard with AMD Duron 800 MHz CPU. The verbose boot log is at
