Sorry. I didn't check CONFIG_ACPI=n. The acpi header file inclusion
is too complicated.

Below patch against 2.6.21+gregkh-pci-pci-reduce-aer-init-error-information.patch
fixes the compiling issue. I delete the acpi header file inclusion in aerdrv.h,
and move function aer_osc_setup to another file.

I tested it with both CONFIG_ACPI=y and CONFIG_ACPI=n.
