The various eepro100 driver releases should soon all have code
similar to
	if (eeprom[10] & 0x0002)
		printk(KERN_INFO "\n" KERN_INFO "  ** The configuration "
			   "EEPROM enables Sleep Mode.\n" KERN_INFO "\n"
			   "  ** This will cause PCI bus errors!\n"
			   KERN_INFO "  ** Update the configuration EEPROM "
			   "with the eepro100-diag program.\n"  );

and the July 2002 release of  eepro100-diag  now has a long usage
message that should make it possible to avoid reading the manual page.

From the CVS log:
----------------------------
revision 2.8
date: 2002/07/15 17:14:06;  author: becker;  state: Exp;  lines: +111 -30
eepro100-diag.c:v2.09 7/15/2002

Added a extended usage message, and tweaked the long option names.

Added flash support and changed MII support to use weak linker symbols.
  The default warning message is shown when the library is not avaiable.
