port-alpha: how to allocate physically contiguous memory?

I'm porting a device driver to NetBSD (and starting with NetBSD/alpha)
I would like to be able to allocate a large chunk (512k or so) of
physically contiguous memory in the driver. 

Other systems (OSF/1, BSDI) have something like contig_malloc() or
vm_page_alloc_contig() for this purpose.  Is there a way to do this in
NetBSD/alpha?

Thanks,

Drew
