Generally,with FreeBSD, the two biggest issues are later Intel video cards, and wireless. For wireless, assuming it has a USB port that you're not using, you can buy the Edimax , about 10 dollars--ah, an Amazon link for $8.99 if you're in the US.

From the description, I"m not sure if this is one of those dual video card laptops or not. If not, the NVidia card should work with the FreeBSD Nvidia drivers. (There's a post on this forum that goes through installing them, better then the somewhat outdated Handbook article.

If there is an Intel card, I'm not sure how the switching works. (I'm not a gamer, so I've never dealt with the 2 video card laptops.) But, you may have to use the vesa driver with the Intel card, which will be slow.
Those are usually the things that cause problems with basic operation. I don't use bluetooth, so don't know how easy or hard it is to get working. Synaptics can also be a bit of a pain. I generally use a tiling window manager though, so that's not much of an issue for me.
