Not that easily, to what i know. You can use the (GUI) tools
at http://www.lightscribe.com to check whether your
drive supports it.

Or for commandline .. as there also is a SDK with a documented API a 
simple tool for this could look like the one i just yet wrote and
attached (be warned, i have no such drive and so this not
tested at all .. just some codepeace of crap that _could_ work
.. at your own risk of course ;-).
But you'll still need the SDK and system libs installed
(from lightscribe.com) for this to work/compile.

If this works for you.. and there are more interested in a commandline
tool like this (that also may get extended a bit to check for 
capabilites like color or monochrome printing etc.) i might build a
rpm in the openSUSE buildservice from it.. so, any feedback is 
appreciated (as always ;-)

Have fun,
Frank

P.S.: Please no flames for the codequality.. i know its crappy. 
I haven't written C++ for ages (at least it feels like that).
