   This probably needs some work for Xen, I can have a look next week-end.
   This shouldn't be hard to implement.

what do you think xen will need?  i think all the bus_dma code
relevant here is shared?

BTW, kjk@ points out that __HAVE_BUS_DMATAG_SUBREGION isn't
strictly necessary as the code will fail to compile if
bus_dmatag_subregion() isn't in scope some how...


someone should try this on the broken PCI audio devices..
