No.  I'm fairly sure that there's no equivalent.  These interfaces
post date the import from NetBSD of the bus_space interface.  We
should likely add them, as they are useful.  They are trivial to
implement on i386 and alpha given that bus_space_handle_t is basically
an int.  On pc98 these will be harder to implement, but shouldn't be
too bad.
