Well, I tried it. It is working. At the moment, my Gateway MX6448 laptop dual-boots openSUSE Linux 10.2 and Mac OS X 10.4.7. I will add Windows XP to the tandem tomorrow. However, there are some considerations. Under OS X, the screen resolution is fixed (1024x768), there is no sound and no network card, therefore no Internet. There's a screenshot of my OS X working on a PC on the desktop customization thread.
