The 3.x -stable kernel doesn't support *ISA* DMA, PCI DMA works just fine ;-) The 4.x -current kernel (what I'm using) supports ISA DMA given newbus isa drivers which can use it, such as the PCM driver & the floppy driver. In fact, after Doug wrote the S/G DMA support for the cia/pyxis chipsets, I implemented it on the other workstation chipsets (tsunami, apecs & lca).
