Hi,  I created a separate Lucid instance to test your changes.  I put it
on the external USB drive and then verified I could recreate the problem
before I installed the kernel images you provided.

I reran the hdparm command to check the read speeds.  The results looked
reasonable.  I was getting approx 30MB/s.  I then tested reading and
writing from the external USB drive to the computer's internal hard
drive and back again to the external USB drive.  Those results too
looked reasonable.  I was getting approx 30 MB/s both ways.  That sure
makes moving GB size files less painful!

Will I have to reinstall those kernel images you provided if Canonical
pushes out another kernel update for Lucid or will your changes be
present in any future kernel updates for Lucid?

Thanks.
