[CentOS] CentOS 5 - Dell Latitude d630 - Vodaphone 3g Card

Hi

I may be forced to move from my mac book pro onto a dell laptop, spit, 
but i sure as heck dont want to have to run windows so.... Does anyone 
know how easy it is to get CentOS to work with a vodaphone 3g card?

I see that it should be possible and a couple of reports of it working 
under gentoo etc but i wonder if anyone here has had any experience of 
this at all?

thanks
