Hello Jeff,
hello all.
I just report that the fresh change in vt6421_set_dma_mode does not
solve (for me) the stable problem described at
http://lkml.org/lkml/2009/10/11/36 "Lots of 6421 setups do not work".
Relaxed reading still works, intensive reading still fails. NB: the
patch had been applied to 2.6.32-rc5 instead of Linux-next.

There are rumors that same vt6421 chips work fine in VIA motherboards; I
haven't any alive one for tests.

The change you refer to only affects the PATA-part of the vt6421, and
you're trouble seems to be with the SATA port. Unfortunately, I don't
have a spare SATA-disk lying around otherwise I could do some testing
and perhaps be of some help.
Groeten,
Bart
