I've got the patch that can be found at http://www.tux.org/hypermail/linux-eepro100/1999-Jun/0010.html
(parts of which I had to apply by hand since I couldn't get the patch to work). This patch is applied against eepro100.c from 2.3.5.
NOTE: EEPROM_SAVE is a typo, I think...it should be EEPROM_SIZE.
I've been trying all night, and from 2.3.99-pre5 to 2.3.25 I could not get it to compile (i'll try 2.3.5 tomorrow). I can't get it to compile to save my soul...I get all sorts of errors against spinlock, or it compiles NOTHING in clients. (And typing make clients says there is nothing to do.) Which means I'm configuring something wrong.
So if anyone has somehow gotten this card to work, could you let me know? I'd like to try to get it working. :-)
