It's actually linuxppc-2.5, the "old" linuxppc_2_5 tree was used when
Linus didn't us bk, it's no longer maintained.

Mostly. A few newer stuffs that didn't make it into Marcelo's 2.4 are
there.

Actually, Cort is no longer maintaining PPC trees. linuxppc_2_4_devel
contains support for more boards and is (slowly) beeing merged into
linuxppc_2_4 and Marcelo as well. It was used as a playground for new
developements when 2.5 wasn't started yet, and is used for new board
support in 2.4 before it's ready for the stable tree.
My rsync kernel (also available as patches against official 2.4 on
ftp.kernel.org) is based on linuxppc_2_4. It contains additional
cutting-edge support for PowerMac machines. It's not really experimental
any more, but some stuffs here didn't make it into the other trees yet
for various reasons. I also have a kernel for experimental stuffs, but I
don't advertise it to avoid adding more confusion ;)
Note that the current maintainer of the entire PPC architecture is Paul
Mackerras (Cort resigned a while ago). I maintain the PowerMac support,
and various other people are involved in support for the bazillion of
boards/platforms supported by the PPC kernel.
