Which version of iasl are you using?  If you're using the version
straight from ACPICA, it needs patching to handle big-endian.

If you're using one of the recent Fedora/Debian versions, they have
been patched for big-endian support, but of course there could be an
issue with those patches.

Regardless, the ACPI data _should_ be in little-endian form.
