A machine with this /boot/grub/grub.conf should for sure not boot 
with "acpi=off". The only idea I have left is that your install is messed up 
with regards to /boot as a partition or as part of /. In any way grub does 
not read the file above when it boots. So what does it read on your 
machine... Maybe you could try a:

 find / -name grub.conf
