DOS ain't dead

Can floppy work in nonDMA mode under DOS/Linux/Windows? (Developers)

Hi,
as I mentioned about LPC here some time ago I have some progress on my project of LPC bus SuperIo expander http://rayer.g6.cz/hardware/lpc_sio.htm
I'm waiting for a PCB from China now.
The question is if and how various OS can work with floppy controller when SuperIO is set to nonDMA mode (I assume that I will be able to configure it for usual legacy IO address so only difference will be in DMA because TPM header doesn't have LDRQ# signal routed on a pin). Is there some kernel config or patches at least for Linux?
I know that HW part is quite easy but FW/SW work will be more complicated. It's just a testing prototype nd challenge for me to make floppy live again in a modern PC (no I don't like floppy on USB).

DOS gives me freedom to unlimited HW access.
