What other things are used for this port and where is it documented? What is the "Get RAM size" command used by? AFAIK, the vmware tools have a EULA that prevents them from being used in QEMU guests. Unless there's an open source driver that uses these commands, I don't see the use of supporting them if the drivers are restricted from being used within QEMU.
