Here are some numbers for you.  Using 2.4.20-pre-10-erik (the
hacked up kernel I happen to be using on my desktop) using gcc
2.95.4 (from Debian testing) and my stock kernel configuration:

bzImage compiled -O2:   1268158
bzImage compiled -Os:   1251431

vmlinux compiled -O2:   3457737
vmlinux compiled -Os:   3437257

/lib/modules/kernel size -O2:  2472629
/lib/modules/kernel size -Os:  2463661

   text    data     bss     dec     hex filename
2354620  316768  258136 2929524  2cb374 vmlinux.O2
2336016  316768  258136 2910920  2c6ac8 vmlinux.Os
