Look for this segment in beastie.4th:
dup bootsafekey @ = if
s" arch-i386" environment? if
s" acpi_load" unsetenv
s" 1" s" hint.acpi.0.disabled" setenv
s" 1" s" loader.acpi_disabled_by_user" setenv
----> s" 1" s" hint.apic.0.disabled" setenv
then
s" 0" s" hw.ata.ata_dma" setenv
s" 0" s" hw.ata.atapi_dma" setenv
s" 0" s" hw.ata.wc" setenv
s" 0" s" hw.eisa_slots" setenv
0 boot
then
