I've finished MIPS4/Big-endian/N32 stages and the stage3 tarball is available on my dev space [1]. Being MIPS4, it's compatible with most SGI machines that Linux supports.
I'd really appreciate some testing and feedback so I can know what to fix. It contains a very modern toolchain (gcc-4.5.1, glibc-2.11.2-r3, binutils-2.20.1-r1) and should give you a good base system. Since it uses the N32 ABI, it should be a bit faster too. :) We don't have any modern netboot or CD images to allow you to boot easily, so if you use something from /experimental/mips/, then your first priority should be to get a bootloader and kernel compiled so the system can be self-hosting. So, go test! (Also, I'm also making MIPS3/Big-endian/N32 stages for SGI systems like R4k Indy and Indigo2. Little-endian stages are on the TODO list.)
