[PlanetCCRMA] would a cardbus to PCI adapter allow laptops to use linux-approved PCI audio cards (Delta66)

I think so; I can't think of a reason why not; probably; I don't know 
enough to be sure.

I really can't overstate how nice RME hardware is. I haven't used any 
hardware based on the Envy24 but there's really no way it could be nicer 
than what RME does.

You should let us know if you get it working, and how it does!
