I’ve put up a tarball of my recent compile of Linux PPC 2.4.20; it contains current patches by Ben Herrenschmidt, with quite a few optimizations and compilation flags through trial and error. ;)

It’s amazingly stable on my Ti, with full internal hardware support built into the kernel, including the Radeon Mobility AGP video, internal ethernet and airport, sound, mouse, etc (minus the modem – that is only avaialble as a module). Filesystems include: HFS+, HFS, Joliet, MSDOS, VFat, ext3, ext2, devfs, et al. It’s also rather fast, to boot. I’m using Gentoo, but it should work on any PPC distribution. Please see the accompanying “README” within the archive. You’ll find it here.
