this is the same issue described on VMware site http://communities.vmware.com/thread/278204
HCL and drivers
and finally RWC2 bundle for linux has scripts for ESX 3.5 and 4, so definitely it is supported. What is completely wrong is java in that RWC2 bundle which crashes. Tried to update Java as X86_64 JRE, but no luck. Services run but RWC2 client didnt see it anymore. Otherwise untouched RWC2 sees the card fine and communicates with until crashes in the console.
So someone should do something about it. Seems as good card but cracky software. But I am not sure if is there anybody interested from Intel? I am giving it a shot and if nobody from Intel will try to do somethin about it, Ill probably return the card to the store. I thought I will never met these kind of problems from Intel itself.
