My understanding is that APCI and APIC are two different things.

I see no messages to /var/log/messages while doing the following (which 
involves rsync'ing a 2618793984 byte file from an NTFS to ext3 drive on 
the same machine:

rubys@rubix4:~/tmp$ rsync /mnt/shared/windows7_7000.iso .
rubys@rubix4:~/tmp$ openssl md5 windows7_7000.iso
MD5(windows7_7000.iso)= 953b9ac92d58f5edef525004bcce048d
rubys@rubix4:~/tmp$ rsync /mnt/shared/windows7_7000.iso .
rubys@rubix4:~/tmp$ openssl md5 windows7_7000.iso
MD5(windows7_7000.iso)= 695328ef1280708eb73303656f6ef0b2

Once again, I'm talking about apic not acpi... does this advice still hold?

I don't believe that's the case.
