Hi!
I installed Jaunty on a Ferrari 4005 WLMi. It was a fresh install because earlier it had been dual-booting with XP so I decided to do a fresh install.
The problem is that about 1/3 of the time, the xserver startup hangs (during boot) and the screen becomes black. The only thing to do is to restart the computer, and after a few restarts it may start working.
The problem is also mentioned (here), but I havent found a fix. I use the open source ati driver.
