What is it supported ?

Monitor :
Wide screen 1920x1200 17" WUXGA X-black is very cool, no problems!
Dri not yet supported from xorg for my video card ATI Mobility Radeon X600 256 MB

Wireless:
WiFi:
Works but you have to install the ipw2200-firmware first.
You need to install the dhcp-client if your network has a dhcp-server.

Note: I have to activate the network interface to make it works. :-) these because I use Gnome and the network graphic tool seems to has some problem activating the interface on the fly.

Bluetooth:
Works.

Audio:
Alsa makes its jobs well. I had some trouble with the microphone, I don't know why but to make it works correctly I must open the mixer (Gnome or Kde) deselect Mic in, select another audio source and then reselect Mic.
At the beginning I had problems wyth Skype ( audio resource busy ) so I could not make multiple calls. At now it works very well and my resource in not busy any more.
As Multimedia System ( Gnome ) it's selected OSS.

Connections:
USB and i.Link work.

Card Dual Pro Reads:
It doens't work. No support at all.

Function Keys:
They don't work. I have followed the instruction on http://popies.net/sonypi/ but I think there is some problem with the kernel module, because dmesg reports this:
Sony Vaio Jogdial input method installed.
Sony Vaio Keys input method installed.

However spicctrl works, in this way you can controll the brightness of you monitor by hand.

DVD/CD:
Works.

I'll find out a way to pint out all the info about hardware that Mandriva is able to identify.
