something we don't want to have.
This patch seems pretty neat.
Please note: this patch includes the
linux kernel module, not only the
dosemu modifications. This is needed
to drive the DMA controller directly.
You won't get it included into an
official kernel - people from XFree
tried that many times, this fails.
Linus doesn't want to provide the
DMA control to userspace I think,
or maybe there wasn't a good
implementation.
But people never give up:

The DMA access might be usefull for
dosemu, but not for sound. It is
good for driving some legacy hardware.

Is there any chance that at least OPL3
support could be added in such a way to Dosemu?
OPL3 doesn't need DMA. It doesn't actually
even need an interrupts. I see no reasons
why the one can't simply open an access
to the OPL3 ports for dosemu and it wont
work. Have you tried?
