how bout adding a menu in firstboot (or something similar during first

and if enabling fails -> display "You are using <cardname>, and it

Please install the proper driver from your vendor and try again
later." - click ok to continue to next screen .. :D
its easy to detect if the card supports compiz or not (query fro GLX_tfp) and enable it if the user has not disabled/enabled it himself.
The problem with such a maneuver (as I bet the Mandriva users are finding out, and the Vista users can testify to) is that there is no really effective way to predict how well the system would perform with Compiz/Beryl on or off; cards that seem fine may actually give horrible results in reality (like my ATI Radeon 9200, which can run Beryl but does so horribly slowly; but a detect would come up positive because the OSS driver can handle Beryl).

For the record my ATI Radeon 9200 runs the shipped version of Compiz at
a perfectly acceptable speed using nothing but what is shipped in F7.
Though lately the decorations has tended to disappear (#228644) but
generally it works nicely and runs at an acceptable speed even on old
hardware like this.

the decoration bug is fixed in upstream compiz.
I'm not convinced Compiz is the key to winning users, sure it's
compelling at first glance but scrolling in your web browser is
painfully slow and it can't handle accelerated video playback so
fullscreen videos turn into a grainy slideshow.
I don't have any of this problems but I am using the nvidia drivers. the oss intel driver should also not have the video problem (uses textured video). also compiz supports composited video which would make videoplayback much faster but it needs to be supported by the players (there are patches for mplayer).
 I think there are
serious problems still to be worked out before this can be relied on
even on hardware we have good drivers for so please don't make the
argument that all we need is to enable such technology to compel users
to try Fedora.. they help but they certainly also currently hurt.
[...]What does Compiz do that
enhances the experience, for me generally it makes the desktop a bit
more fun but when push comes to shove the scale plugin is what I use the
most. I think we need to make Compiz do more useful stuff in addition to
the incredible cracktastic funfilled bling it does currently.

compiz will be able to do alot more things when input redirection is finished in xorg.
