Dan Malek has provided the functions consistent_alloc(), consistent_free(),
and consistent_sync() for uses other than PCI.  They are in linuxppc_2_5
rev 1.446 and later (I'm not sure if they are in any earlier version).
They are also in my active development kernel, but not yet in any kernel
that I have put on my ftp site.
