that's no longer the case since Tuesday :-)

pci_alloc_consistent will now fail on PCX-S and PCX-T machines.  PCX-L
and PCX-L2 machines set the hppa_dma_ops to succeed (use Uncacheable
pages) and PCX-T', PCX-U and upwards all have IOMMUs that will set the
hppa_dma_ops to something appropriate.

i'm sure that the tables in the kernel for mapping from hversion to cpu
type are currently broken.  i'm going to fix that today (now that i have
the tables we're currently using in the hwdb).
