I don't know how it's handled in the current code. The Atari driver
carries a big fat warning from the original author that the Falcon (my
test box) cannot do scatter-gather at all, due to problems with DMA setup.
If sg_tablesize==1 is equivalent to not using scatter-gather, I can try
settin 1 there (but why isn't SG_NONE defined as 1, then?)
