Oops.  Sorry about that.

UDMA has been available in -CURRENT for about a year.  I suspect that
the reason it hasn't been retrofitted to 2.2 is because it's too much
of a change.  There was an attempt in April, but it didn't make it.
Since everybody's working on 3.0-RELEASE at the moment, I don't
suppose that will change for 2.2.7.  That's a pity: as you can see,
the difference is significant.
