+	Part of Radeon driver
+	
+	Fast logger
+	
+	As syslog is very slow and tends to loose
+	data if its buffer overflows (which occurs much
+	too often), this module provides a fast (and memory-
+	wasting) logging mechanism. You need a seperate 
+	application to retrieve the log.
+	
+	Everything is thread-safe.
