Possible?

Yes but only in special circumstances. Because you can write an operating system in Java and C#, and then, should be able to write device drivers for it. The memory hit to these drivers and operating systems would be substantial.

Probable?

Not likely. Atleast not in the world of Windows or MacOS or even Linux... At least not anytime soon. Because languages like C# and Java depend on the CLR and JVM. The way these languages work means that they cannot effectively be loaded into ring0.

Also, the performance hit would be rather large if managed languages were employed in device drivers.
