They (drivers) don't, but what if we start giving them routing for
64-bit DMA? AFAIU they treat 64-bit DMA as 32-bit one (according to
specs: "If 64 Bit isn't an option, Silicon Backplane and PCI-E buses
can use 32 bit DMA.").

Won't they start using 64-bit DMA in the 32-bit way but with 64-bit
routing bits?
