Minimal CPU for i586 Tumbleweed?

Hi all, what is the minimal suitable CPU type for openSUSE Tumbleweed (I know that i586 is deprecated / less supported, but I guess there is still a "minimal viable target system" for it)? I updated a Pentium-M (Dothan, probably) based Toughbook CF-51 and after finding that I need "rodata=off" kernel parameter for the kernel to even boot, it fails miserably later in userspace apparently (it just hangs). So before I'm filing bug reports, the question is if this is still supposed to work.
