I modified my linux kernel (based on 2.2.16) in linux/fs/binfmt_elf.c to emit:
	elf.e_ident[EI_OSABI] = ELFOSABI_LINUX;
The linux-2.6 series does this.

This seemed to help in conjuction with changes to gdb/arm-linux-tdep.c to add:
set_gdbarch_regset_from_core_section(gdbarch,arm_linux_regset_from_core_section);

I can send in a patch for the arm-linux-tdep.c changes if you'd like.
