Here's my numbers from the latest changes. They are not as big, perhaps I had debug enabled too. I took a debian 3.0 config, enabled jump labels and some tracing, did a make localyesconfig (something broke it as the config still had modules that I had to manual convert to =y). Here's the results:
gcc 4.6.0
text data bss dec hex filename 14355064 1810272 5722112 21887448 14df9d8 vmlinux 14354490 1810400 5722112 21887002 14df81a vmlinux-patched
It's only a 574 byte savings. That's not much. I wish I had the config I used the first time. I may have had debug on that gave it a bigger impact.
Attached is the config:
