They work just fine on most platforms with 32-bit addresses.
The issue is with what the SGI platform can support, not what
the PCI-X devices can support.

BTW, adding consistent_dma_mask to struct pci_dev and a
corresponding pci_set_consistent_dma_mask() is a good idea.
I think it would simplify our SBA code a bit.

thanks,
