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
