You are correct, Andrew: ES7000 "preferred" mode is ACPI (although it
runs in MPS as well, which we use for debugging of intermittent ACPI and
platform problems).
I have done a similar patch (see
http://bugzilla.kernel.org/attachment.cgi?id=5771&action=view) against
2.6.13, but the one suggested later by Peter Hagervall  
http://www.ussg.iu.edu/hypermail/linux/kernel/0510.3/1302.html was
actually taking care of the compile problem through Kconfig better,
since "acpi=off" option is available for our debug/testing purposes
anyway.
Thanks,
