  * Changes:
- *	Thomas Bogendoerfer ([email protected]):
+ *	Thomas Bogendoerfer ([email protected]):
  *	- added support for Linux/Alpha, but removed most of it, because
  *        it worked only for the PCI chip. 
  *      - added hook for the 32bit lance driver
  *      - added PCnetPCI II (79C970A) to chip table
+ *      - made 32bit driver standalone
+ *      - changed setting of autoselect bit
  *
  *	Paul Gortmaker ([email protected]):
  *	- hopefully fix above so Linux/Alpha can use ISA cards too.
