Comment:
I just confirmed this with the Dapper Flight 4 Live CD. Here are the
steps I went through to reproduce:

1) download dapper flight 4 live cd and burn it
2) boot
3) change DefaultDepth in /etc/X11/xorg.conf to 16 ( my T30 only has 16M of ram and a 1400x1050 screen, so direct rendering is only available for 1400x1050 at 16 bits)
4) restart gdm
5) load up the gnome-screensaver-preferences and select the GLText screensaver and note how it flickers
6) run gnome-screensaver-command --activate and see the flickery badness
7) sudo apt-get update && sudo apt-get install xscreensaver
8) run xscreensaver-demo and select GLText
9) hit Preview and note the lack of flicker.

Again, this is on my Thinkpad T30 with this card (as told by lspci):
