(I searched, but I have not seen this posted to the list before.)
Non-modular support for 3Com EtherLinkIII cards, specifically the ISA
3c509b, worked fine in kernel 2.2.18.
CONFIG_EL3=y
What worked in kernel 2.2.18 does not work in kernel 2.4.1 however.
http://groups.google.com (deja's successor) reveals that multiple
systems are having this problem, but there are no solutions listed
there (at least not among the English posts. I don't speak German,
but apparently many Linux users do.) I've spent quite a number of hours
attempting to resolve the matter, but with no success either.
Search for "Linux 2.4 3c509" shows the follow excerpts among the responses:

I get the same here.

Again, similar results here. Incorrect port in 2.4.1 but correct in 2.2.18.

While my other NICs differ, the end result is that the 3c509 does not
work, yet the other NICs do, which is as I have experienced as well.
At the LILO prompt, I pass parameters as follows:
LILO boot: Linux241 ether=10,0x300,eth0 ether=7,0x320,eth1
and the (NE2000 clone) eth0 card works fine, but the 3c509b eth1 card does not.
LILO boot: Linux241 ether=7,0x320,eth0 ether=10,0x300,eth1
is not a solution, and merely causes the ethX values to flip-flop,
with the same failure. (Anticipated, but I'm mentioning it in case it
matters to anyone.)
And of course, I should mention that
LILO boot: Linux2218 ether=10,0x300,eth0 ether=7,0x320,eth1
works just fine, with the NE2000 clone on eth0 *and* the 3c509b on eth1.
(LILO boot: Linux2218 ether=7,0x320,eth0 ether=10,0x300,eth1
functions as expected as well, with the flip-flop and both cards working.)
There are features of kernel 2.4.x that I consider necessary (including,
but not limited to, netfilter) so using kernel 2.2.18 is not an adequate
solution here.
I've tried recompiling the kernel stripped down to bare minimums for
testing, but nothing seems to resolve this. I've also tested the kernel
on both a 486dx33 and a PII400, with the same results. I've also tried
using this as a single NIC in the ether=, for testing, even though
that is not a satisfactory situation here. Again, failure. I've even
physically removed the other NICs from the machine and acheived no success.
I don't see this driver mentioned in MAINTAINERS so I'm filing this
bug report to the list. (I'm uncertain if this is Donald Becker's
"baby" currently or not.) I'm omitting dmesg and .config etc. since
it doesn't seem to be necessary; anyone with a 3c509b will probably get
similar results with a 2.4.x kernel. If needed I can send any specifics
upon request.
