DELL XPS M1330 and Ubuntu 8.04

Hello,

I was wondering if anyone knows how to get the wireless card, sound card, hibernation, loud fan and the top buttons to work under Ubuntu 8.04?

According to to lshw, here's what I have:

  *-network UNCLAIMED

Any suggestions on how to get these things to work? The NIC seems to work fine though.

Thanks!
