Well, that is for the legacy grub (which openSUSE still uses, BTW, or at 
least in 11.4). Nils gave me the insight, and what you do is to alter 
the entry in /etc/default/grub to read

GRUB_CMDLINE_LINUX="libata.force=X:80c" where X is the line being incorrectly set by the kernel. In my case I typed in 'libata.force=2:80c'.

The run 'sudo update-grub'. On the next reboot the UDMA will be set correctly.
