After several hours compiling and waiting for a chance to restart X, finally I got X.org 6.8 running with drop shadow and transparency. These are what I did to achieve that under Gentoo Linux.

1. Unmask X.org with these lines under /etc/portage/package.keywords:

   =x11-misc/ttmkfdir-3.0.9-r2 ~x86
       =x11-base/xorg-x11-6.8.0 ~x86

2. Install X.org at least with these (new) USE flags: dmx xprint
3. Edit your config file (/etc/X11/xorg.conf), and add the following lines:

   Section "Extensions"
           Option "Composite"  "Enable"
           Option "RENDER"     "Enable"
       EndSection

4. Also add Option "RenderAccel" "on" on your Device section, mine is like this:

   Section "Device"
           Identifier  "NVIDIA GeForce4 Ti 4200 (AOpen)"
           Driver      "nvidia"
           Option      "DPMS"  "on"
           Option      "RenderAccel" "on"
       EndSection

5. Emerge both xcompmgr and transset, both are ~x86 masked, I took the easy way by emerging the ebuild files.
6. Run xcompmgr -c to enable drop shadow. I just put symlink to it under ~/.kde3.3/Autostart.
7. You can make a window transparent by executing transset, and then clicking on the window you want to make transparent.
8. Enjoy!

Thank to all the folks that posted various information at Gentoo Forums.
