I found the answered buried in [this post][1]. The new setpci command is sudo setpci -s 00:03.0 0x7b.b=19 btw, this setting isn't "sticky" and won't persist across reboots-- it has to be set upon each boot. You can put this command in a bash script and run it on startup. See [here][2] for details on start-up scripts.
