I tried search for what SLED 11 supports, but could not get a plain list.
My guess is that it would work with i7 Nehalem, provided you have graphics card, sound card, ethernet card made before 2008.
Is anybody still running opensuse 11, and on something new?
You won’t get that list. It’s impossible to gather every bit of info needed, where lots of hardware manufacturers don’t want to share this info.
Plus, openSUSE 11.* have all reached their end of life.
Plus, SUSE (SLES/SLED) is not openSUSE.
EDIT: forgot
