Ok, so I am going to take a look at the datasheet for the southbridge. I wonder if DDMA support is disabled by default and there need to be a utility made to change a chipset register setting to get it to work.
Edit: Ok, so according to page 61 of the datasheet, DDMA is disabled by default.... and if the BIOS doesn't enable it, then that would explain why it isn't working.

So I am going to look into making a utility that can change the register settings to enable it and see if that works. Since I have a board with the 586b chipset that seems to also have the issue, I should be able to test on that. If it works, then that should not only help the YMF based cards but other cards that use DDMA.
