What you're looking for is called 'MAC address filtering' and I
imagine it is very doable.  Having never done it before myself (with a
Gentoo router) the best I can do is point you at Google and wish you
the best of luck.

It's been a little while since I worried about my WPA2 wireless
getting hacked.  Apparently, a vulnerability in TKIP was recently
discovered that made WPA2 networks using that encryption less secure.
It would still take a lot of doing on the attacking party's end to do
it though.  Have you considered setting up WPA2 Enterprise, with the
RADIUS server and whatnot?
