Gateway x6421 driver issues

I just installed RC1 onto my Gateway notebook (mx6421), and there are there 3
devices that I can't seem to find drivers for or at least updated drivers
for Vista. Here is the list of them; Mas Storage Controller, Multimedia Audio
Controller, and my PCI Modem.

If anyone has been having the same issues let me know if they have found a
soultion. Or if there are no soultions, my assumption is there just aren't
driver support for these devices.

Thanks
