+Subject: [v2] libertas: prioritize usb8388_olpc.bin firmware on OLPC machines
+Date: Thu, 04 Aug 2011 23:06:52 -0000
+From: Andres Salomon <dilinger at queued.net>
+
+Normally, the v9 firmware will be loaded if it's available.  However, on
+OLPC XO-1 machines, the olpc-specific firmware supports extra functionality.
+This makes the libertas driver attempt to load the custom firmware first
+if the machine is an OLPC machine; if that fails (or it's not an OLPC
+machine), fall back to attempting to load the other firmwares.
