Before I can answer it, we need to resolve the installation problem
for this platform with 5.3-RC2. The current installation is panic at 
MADT start up.
I tried a few times, but got the same problem.
Following is the console output during this installation boot up:

...
avail memory = 511500288 (487 MB)
ACPI APIC Table: < ASUS P2B-DS  >
ACPI disabled by blacklist. Contact your BIOS vendor.
MADT: ACPI Startup failed with AE_ERROR
Try disabling either ACPI or apic support.
panic: Using MADT but ACPI doesn't work

Would any one please provide a solution or suggestion on how to
make 5.3-RC2 installation proceed on this host ?
    ASUS P2B-DS dual Pentium-III 450 MHz

I looked at BIOS, but did not find anything that can disable APIC.
