+	 * A0000-FFFFF region - If we wish you mmap the linear aperture
+	 * it requires a device driver.
+	 *
+	 * So what we'll do is use /dev/vtXX for the A0000-FFFFF stuff, and
+	 * try to use the /dev/fbs/aperture or /dev/xsvc driver if the server
+	 * tries to mmap anything > FFFFF.  Its very very unlikely that the

+	 * by /dev/vtXX.
