This is probably more of a feature request than a bug report. My apologies if this is not the appropriate place to report it. I have a Belkin 3-button classic mouse using its PS/2 -> serial adapter ($8.95 at Egghead/Onsale). The mouse probe fails, forcing a text installation. I'd really appreciate being able to tell it what kind of mouse I've got, run the X test to see if I got it right, and then let me do a GUI install. Thanks!
It's a bug in the installer; it's been fixed.
