Try man acpi:
     To disable the acpi driver completely, set the kernel environment vari-
     able hint.acpi.0.disabled to 1.  Some i386 machines totally fail to oper-
     ate with some or all of ACPI disabled.  Other i386 machines fail with
     ACPI enabled.  Non-i386 platforms do not support operating systems which
     do not use ACPI.  Disabling all or part of ACPI on non-i386 platforms may
     result in a non-functional system.

Hints can go in /boot/loader.conf.  Later, after the system is working for
you, you can go back and install a new BIOS and see if that fixes the
problem with ACPI enabled.
