You should send this to the linux-arm-kernel@...ts.infradead.org
mailing list.

FWIW, 2.6.35-rc1 boots fine on my ixp4xx NAS box.

You should also investigate if this is a regression from earlier
kernels or not. If you can't compile and boot earlier kernels
either then it may be a problem in your build tools or build procedure.
For starters, are you building with the correct endianess, and
are you sure you don't need a kernel shim to correct the bootloader's
machine type?
