Linux2.4 for Nios2

Is there Linux2.4 kernel for Nios2? I found <niosnommu> in Linux 2.4 kernel, but I am not sure whether nios instructions is compatible with nios2&#39;s.

The project needs <sysvipc> in Linux2.4, which is not a default function in Linux2.6.

So could you give me advice about Linux2.4 for Nios2?
