Mm, entering the twilight zone? Here is the configuration which works here:

CPU:   AMCC PowerPC 440EPx Rev. A at 528 MHz (PLB=132, OPB=66, EBC=66 MHz)
...
Board: Sequoia - AMCC PPC440EPx Evaluation Board, Rev. F, PCI=66 MHz

$ type ppc_4xxFP-gcc
ppc_4xxFP-gcc is /opt/eldk-4.1/usr/bin/ppc_4xxFP-gcc
(works with 4.0 and latest the same way).

>>From a cloned Denx's GIT baseline:
$ git checkout -b sequoia 208aa3df8645608ff3febb65f83219173dfe4979
$ ~/xenomai-trunk/scripts/prepare-kernel.sh --arch=ppc --linux=.
... accept the default suggestion, i.e. adeos-ipipe-2.6.23-ppc-1.6-00
$ make ARCH=ppc CROSS_COMPILE=ppc_4xxFP-gcc sequoia_defconfig
... use all default Xenomai options
$ make ARCH=ppc CROSS_COMPILE=ppc_4xxFP-gcc [uImage]
