The system hangs before the while loop. Adding more debugging I found out it 
hangs exactly at the call to AcpiHwWritePort():

        Status = AcpiHwWritePort (AcpiGbl_FADT.SmiCommand,
                        (UINT32) AcpiGbl_FADT.AcpiEnable, 8);


I've attached dmesg from Ubuntu 9.x booting on the same machine. Anything more 
you want me to try?
