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.

The default warning message is shown when the library is not avaiable.
