I tested dd times for a large ISO:
sudo time dd if=ubuntu-10.04.4-dvd-amd64.iso of=/dev/sdb 2.6.32-40-server 18:57 2.6.32-41-server 18:42 2.6.32-40-generic 27.68 2.6.32-41-generic 20:24
Given the improvements, and no noticeable regression, and the fact that this patch has been in Oneiric for awhile, I'm marking this as verified.
