If anyone would like to nurture these patches he is more than welcome.
ps: you also have pv-dma option for Linux guests (same status though).
As time goes by most host will have either vt-d or amd iommu.

Hmm.  Well, as time goes by, most hosts will be 64 bit or more.
But it does not mean that there's no need to maintain 32bits
arch anymore...  i hope anyway :)

But of course
Are you saying that PCI passthrough without hardware support will
not be available in (standard) kvm, even if patches exists for that?

No, just might take a some time to go to mainline. Patches need further polishing and we
also need wider demand for it.
Actually pvdma can help vt-d so we won't have to make all the guest memory unswappable.
