Retaining kernel boot parameters in openSUSE

Another caveat
After a kernel update, I found that the 'nomodeset' argument was missing in the kernel boot line (see this post). I understood from a beginning line of /boot/grub/menu.lst, that I had to add the arguments to the file '/etc/sysconfig/bootloader' that I needed to be retained across kernel updates.

Mercy of Sathguru
When I opened that file (/etc/sysconfig/bootloader), I noticed that a variable 'DEFAULT_APPEND' was tagged with a description that suggested that I add the 'nomodeset' to the list of arguments it already had. I did that and it worked!!
