hmm... according to the specs, it looks like it could be an agere, atheros, or a toshiba blue tooth kit. not sure. any way you can find that out? my guess it's the atheros since the agere is only 802.11 a.

anyway, looks like both agere and atheros have support for linux, but i don't know about their integrated card kits.
maybe give this a read through.

i'm not knowledgeable at all about wireless on linux laptops so i'll bow out now.
