Why? 2.4.4 ist very, very old. Use a more recent kernel tree. If  you
want   to   stay   in   our   source   tree,   then  please  use  the
linuxppc_2_4_devel module on our CVS server.

Then your configuration is broken. The kkernel compiles fine for many boards.

This is not a big surprise. The "bseip.h" header file is for a MPC8xx
based board - what makes you think that this might work on your  8260
based hardware?

No. There is no patch needed. The kernel trees are  clean.  You  just
have  to  select a correct configuration. Ummm... and for your custom
board you will probably have to port Linux first.

See for example the linuxppc_2_4_devel module on our CVS server.
