We have a usenet server we use with 2.6.6 kernel and the eepro100 gives
IRQ problems:

May 16 01:35:58 enterprise kernel: eepro100.c:v1.09j-t 9/29/99 Donald Becker http://www.scyld.com/network/eepro100.html

Where as the e100 is rocksolid (knock wood) under sometimes heavy load:

irq  9:         0 acpi                  irq 19:  22025755 ide2, ide3    


So _i_ would advise the e100 driver.
