System V/Xenix/V7/Coherent file system support (CONFIG_SYSV_FS) (tristate)
Here's a config option straight from the latest kernel (2.6.20). It may or may not be what you are looking for. Unfortunately these sorts of things were well before my time.
So if its in the kernel then theres a good chance theres a distro with it. I would suggest Debian/Debian based distros, their kernels have a fairly broad scope.
Worst case scenario you could recompile the kernel and include the config option yourself.
