Laptops That Support FreeBSD/Win/Linux/Solaris?

whirred asks: "I often hear about certain laptops being particularly bad or ideal for particular operating systems. I want to purchase a laptop with around 30 gigs of hard drive space, and when I do, I want to be able to use FreeBSD, Linux, Win32, and Solaris on Intel. I would also like to possibly install BeOS or OpenBSD. Not being an expert on any of these operating systems, is there a laptop out there that has hardware that is supported by all of these operating systems?"
