This appears a result of changes in:

   arch/i386/kernel/vmlinux.lds.S

which causes the kernel start address to
change from 0xc0100000 to 0x100000 causing
objcopy to gag.  I rolled back to a 2.6.8.1
version of the above linker map file and did
get the kernel to build and [mostly] boot.
However it incorporated Ingo's RT patches and
wasn't exactly a vanilla 2.6.9-mm1.

While I don't recommend the above as a fix,
a repeat of the experiment will require adding
the following to the linker text section:
