Vaio PCG-N505SN
All hardware without exception works perfectly under Knoppix:
Bootable external PCMCIA CD-ROM
Firewire
Infrared IRDA
Sound
Screen Brightness Control
Video with xv accelleration
Wireless LAN with Orinoco Gold card
PCMCIA modem
Standby to RAM

The only thing is that I couldn't get it to hibernate to disk yet.
