We currently don't have support for ISA DMA, which the legacy floppy
driver (as opposed to USB floppy) requires.
Not sure how best to fix this. We could rejig the memory layout to give
dom0 the bottom 16MB (as opposed to its current bottom 1MB), or
alternatively perhaps it would be sufficient to build an isa dma zone
out of free pages in the bottom 1MB.
Perhaps someone who cares about ISA DMA support could volunteer? I
personally haven't used a floppy in years...
