As the Ebuyer spec doesn't mention it, then you probably don't have it
available. Contrast this with my EEEPC where the spec said it had
bluetooth and when I installed Ubuntu on it, the bleutooth icon was
there next to the network icon (and it works!).

I have googled for something and found at least one reference to a
laptop with this chip that had a Broadcom bluetooth chip as well -
hardly needed if the RTL8191SEvB would do the job on its own.
