Even if they don't have an official support team behind an operating system, there is no reason that the laptop, which is of a standard x86 architecture, won't boot. It wasn't made clear whether installations were intentionally blocked, though I imagine they weren't, or whether it's just broken hardware that won't let you boot FreeBSD. I have to wonder what sort of design went into a laptop to make it break in such a way that makes it incompatible from a standard x86 architecture in such a way. Really, this sort of thing isn't that difficult to support.
