9.1-RELEASE AMD64 crash under VBox 4.2.6 when IO APIC is disabled

[CeDeROM]

Hey :-) I have just noticed that booting installation media for
FreeBSD 9.1-RELEASE AMD64 from ISO bootonly under VirtualBox 4.2.6
results in a kernel panic both when ACPI is enabled and disabled in
the boot dialog screen (seems different cause of crash), when IO APIC
is disabled in VBox (which is a default). I thought AMD64 is not
related to APIC..?
Best regards :-)
