Its just further evidence that developers outside of Linux for open-source operating systems like Solaris & the *BSD really need to work together on graphics drivers development in creating some form of easily portable platform across systems, so no matter what graphics driver is available the moment it is ported to an OS outside of Linux it only requires a small amount of modification to get it onto the other OS platforms.
For example: All most all open-source operating systems are running some form of X-org, that is the denominator that is universal across all open-source operating systems. So surely there has to be a way that OS's could take advantage of it for graphics drivers. Unless you use some other platform like Java.
