+    fmvj18x_cs.c 2.8 2002/03/23
+
+    A fmvj18x (and its compatibles) PCMCIA client driver
+
+    Contributed by Shingo Fujimoto, shingo@flab.fujitsu.co.jp
+
+    TDK LAK-CD021 and CONTEC C-NET(PC)C support added by 
+    Nobuhiro Katayama, kata-n@po.iijnet.or.jp
+
+    The PCMCIA client code is based on code written by David Hinds.
+    Network code is based on the "FMV-18x driver" by Yutaka TAMIYA
+    but is actually largely Donald Becker's AT1700 driver, which
+    carries the following attribution:
