You need to have your uncompressed compiled kernel, usually
/usr/src/linux/vmlinux. Use the following steps:

gdb /usr/src/linux/vmlinux

[...]
(gdb) disassemble 0x001ae9a0
<assembler dump follows for this function>

If you compiled your kernel with -g, you could list and call by function
names. Please explore to your hearts content. You may find a debugging
tool such as DDD to be handy for showing structural layout and such.
