# mips64-unknown-linux-gnu-ld --version
GNU ld version 2.16.1

# mips64-unknown-linux-gnu-gcc --version
mips64-unknown-linux-gnu-gcc (GCC) 4.1.1 (Gentoo 4.1.1-r3)

And the disassembly of vmlinux.32 for the handle_int function is attached.

I haven't built a kernel w/ gcc-3.x for some time, probably last time being when 
I was chasing down the strange funkiness in my Octane's userland in 2.6.19.
