this system is an AMD Duron based system.  FreeBSD 6.0 ran just fine with no
problems.

	
>Description:
	

on boot, there are many acpi "bad write" and "bad read" warnings on this
particular machine.  after booting, there are no obvious problems in normal
operation, but it is a barely used test server.

The /var/run/dmesg is here, but it appears truncated.  The fxp0 device doesn't
show, for example.

boot 6.2 kernel on this particular system.  it doesn't happen on my amd64 box
running same source but compiled for amd64.

State-Changed-Why:  
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 
messages. 

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.
