bootchart works fine for this. What I've done when I was looking at
login speed recently is to
run

bootchartd start

on the console before logging in, and then I have an autostart file to
stop it once login is done:

[Desktop Entry]
Name=Stop bootchart
Exec=gnome-terminal -e "sh -c 'sudo bootchartd stop; sleep 30'"
Terminal=false
Type=Application
X-GNOME-Autostart-Phase=Applications

You can probably do without the terminal as well...
