"Ultra DMA TX patch" + "Generic DMA patch" = "Generic Ultra DMA patch"
However I don't have any "Ultra" hardware (not even an Ultra Sparc .-( ),
so I can't test it. But I won't be surprised if this would work, too.
Except for some of those printk lines in this patch, which I suspect to
produce "random numbers" on the screen with non-Intel chips.
