I see it now, at least on 2.6.18-era kernels. It doesn't seem to happen with earlier RHEL4 (2.6.9-era) vmlinux files for some reason. And on anything later than 2.6.20, the code in question isn't run. Anyway, as you tracked it down, the x86 code disassembly output is different, but should be trivial to fix.
