The patch is now distributed in the beta ide-udma driver for 2.2.x
(http://www.dyer.vanderbilt.edu/server/udma/) and it gives me ~6MB/s vs.
~1.5MB/s (hdparm -t) on my 164sx. Integer performance on a pc164sx/533
should be about the same as a pII/350 (floating point much higher on
anything but linux).
