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:

Linux 2.6.6-bk2 (root@enterprise) (gcc 3.3.3 ) #1 Sun May 16 10:50:59 CEST 2004 1CPU [enterprise.cistron.nl]

Memory: Total Used Free Shared Buffers

irq 0: 250377255 timer irq 12: 3
irq 1: 3 irq 14: 11055492 ide0
irq 3: 2 irq 15: 11058878 ide1
irq 4: 193 serial irq 16: 27773698 sym53c8xx
irq 8: 3 rtc irq 18: 996592375 eth0
irq 9: 0 acpi irq 19: 22025755 ide2, ide3


So _i_ would advise the e100 driver.
