Well, since I'm a known glutton for punishment. ;)

a 2.6.11-rc3-RT tree I had handy from last night shows about a 0.5% size reduction:
text data bss dec hex filename
3033417 680824 436188 4150429 3f549d vmlinux.before
3017443 681068 436188 4134699 3f172b vmlinux

Am running a 2.6.11-rc3-mm1-RT kernel with it applied, and have probably 40-50
hours of uptime on it with no noticed issues on a Dell laptop. Sorry, don't
have any comparative performance stats...
