Note: it won't work with i386. Please let me know if it works for you.

1. Update to 7-stable (both kernel and userland)

As drm information for RADEON X1650 (etc) are not updated, in the 7.1-RELEASE, first, update the kernel and userland to later than SVN rev 187021 (2009/1/10) version.

2. patch /etc/X11/xorg.conf

In my case hald somehow doesn't work well, so I added

as well.

3. install compiz
portinstall x11-wm/compiz-fusion
portinstall x11-wm/emerald

4. start compiz+emerald by:
$ LIBGL_ALWAYS_INDIRECT=1 compiz --replace ccp &
$ emerald --replace &

6. Note on i386
It doesn't work on i386. sometimes screen is garbled. sometimes
