What is the last thing printed before the boot hang? 
If it prints nothing, please attach the output of acpidmp 
available in /usr/sbin/ in in pmtools here: 
Any change if you boot with "pci=noapic" or "noapic"? 
Does any other Linux version with ACPI enabled work? 
(eg. FC2-test1, FC1 with "acpi=on", or 2.6.5) 
Also, please verify that you have the lastest BIOS.
