  *         rewritten PCI card detection
  *         added dwio mode to get driver working on some PPC machines
  * v1.21:  added mii selection and mii ioctl
+ * v1.22:  changed pci scanning code to make PPC people happy
+ *         fixed switching to 32bit mode in pcnet32_open() (thanks
+ *         to Michael Richard <mcr@solidum.com> for noticing this one)
+ *	   added sub vendor/device id matching (thanks again to 
+ *	   Michael Richard <mcr@solidum.com>)
+ *         added chip id for 79c973/975 (thanks to Zach Brown <zab@zabbo.net>)
+ * v1.23   fixed small bug, when manual selecting MII speed/duplex
