Mike Smith da8bb3a3bf Update to the latest development version of the Mylex driver. Changes in
this version include:

 - Support for version 2.x firmware (2.42 or later recommended).  This
   means we are the only open-source driver supporting these adapters.
   This code has only been tested on a Digital KZPCA adapter in an Alpha
   system, but is believed to be correct.  NOTE: EISA adapters are not
   yet supported.

 - Support the BIOS/Firmware initialisation handshake protocol.  This
   allows the driver to bring the card up to operational state even if
   the BIOS can't be run (eg. if it's an x86 BIOS in an Alpha system).

 - A working command pasthrough interface.  This allows a user-space
   configuration tool (under development) to issue arbitrary commands
   to the controller or to devices in the system.
