Yeah, I ifdef'd them out after noticing they weren't used at all.

I now got a link failure:
 
linking kernel.debug
evevent.o: In function `AcpiEvInitialize':
ACPI_ADR_SPACE_SETUP/../../../contrib/dev/acpica/evevent.c:168: undefined reference to `AcpiEvGpeInitialize'
*** Error code 1

I'll keep you posted...

You probably should be using a cross-compiler for cross-builds :-)

The acpi module does not build on ia64 at all. ACPI is non-optional
on ia64, so there's no need for a module. It may not be a bad idea
to make the module buildable for testing purposes, but it will not
be useful beyond mere building.

The best way to cross-build is by starting a cross-world, which you
then abort after the headers are installed in the object tree. This
should leave a usable set of cross-tools you can use for buildkernel.
