It came originally from the PowerPC world, but there is now Sparc implementation
in the kernel tree. We're working on using device tree for MIPS and, according to
a participant at the OLS Device Tree BOFS, someone in the ARM world is also
working on an implementation. I don't know how much work it would be to backport
to 2.4, but my guess is that it's pretty independent of the kernel version.
There is now a device tree mailing list independent of PowerPC. You can find more
