This patch which was posted to linuxppc-dev should fix your bug:

From: Kumar Gala <galak@kernel.crashing.org>
Date: Tue, Jan 6, 2009 at 11:00 PM
Subject: [PATCH] powerpc: Export cacheable_memzero as its now used in a driver
To: linuxppc-dev@ozlabs.org


The Freescale PowerPC specific gianfar driver (gig-e) uses
cacheable_memzero for performance reasons we need to export
the symbol to allow the driver to be built as a module.
