Hello,
<i>Does Sun have drivers for any 3rd party wireless ethernet cards ?</i>
The Ultra 5 is not a SPARCstation (SPARCstations used S-Bus).
No, there aren't any Solaris drivers for wireless cards. Even Solaris 10 x86 lacks the support in the GA release (drivers for Solaris Express x86/OpenSolaris are coming).
If you want to integrate your SPARCstation/Ultra/Blade/etc. into a wireless network, devices <i>like</i> the Asus WL-330G Wireless Access Point + Ethernet Adapter are already available.

Maybe you can review Tadpole's website (or Sun's, who sell some of Tadpole's portable systems). If I remember corectly, they offer a <b>system</b> with wireless support (11MB, not 54MB).
