NEWS on installing Debian on my Amilo Mini Ui3520...
I've installed Debian Lenny (stable) 5.0...

Nearly everthing works out of the box exept the Wifi and some special buttons like brightness and wifi-on button.

To get everything running just "rmmd ath5k" and "insmod ath_pci" then the wireless-card will work properly. Only problem is that the wireless switch isn't working but you can enable/disable in your BIOS settings.
Got the latest BIOS installed. 1.10 or somthing like that ;)

Sound works out of the box but the mic didn't work so I had to install alsa 1.17. Webcam just works.

Have a nice day
