I have similar problem with 3C90x card.

I traced DHCP dialogs  of linux (RH9), WinXP and Aos (latest crazy 
release) with two  different cards.
I used ethereal program on linux to capture packets.
Card---> 3C905 100Base TX [Boomerang] vendor/device: 10B7 / 9050
Old card---> 3C905B vendor/device: 10B7 / 9055

Captured files as follows and attached:


myAosOldcarddhcp.out (with Old card)
myAosdhcp.out

myXPdhcp.out

mylinuxOldcarddhcp.out (with Old card)
mylinuxdhcp.out
