+    trivial: try harder to make sure mtdram is set up
+    
+    the autopkgtest environment in Ubuntu seems to not be preparing the mtdram
+    device properly. Sometimes the udev node "exists" but the /dev/mtd0 does not
+    exist.
+    
+    Look for this explicitly and skip the test if it happens.
