David,
Thank you very much for your help, it took me a while to digect it, plus other
things changed as well.
Most importantly -- DHCP is not the source of my problem. Our computer admins
assigned me a static IP address (with a subnet mask, gateway and 3 DNS servers), but
the story is the same -- it works under Windows (I plugged the IP numbers instead of
DHCP, just to see that it works in Win), but not in Linux...
I've done networking setup many times since, through linuxconf and directly editing
/etc/hosts, /etc/resolv.conf, etc... I start to think that there is a problem with
the card setup.
Maybe a bad IRQ sharing? Is there any way to run some diagnostic in Linux to see if
the card
setup is ok?
I am grateful for any suggestions...

No, it seems it is the other way around -- modprobe seems to look for a .o.gz
file. I uncompressed the 3c90x module (btw, all modules in drivers are compressed),
and then modprobe couldn't find it:
[root@botik net]# pwd
/lib/modules/2.4.3-20mdk/kernel/drivers/net
[root@botik net]# gunzip 3c90x.o.gz
[root@botik net]# cd ..
[root@botik drivers]# ll net/3c*

-rw-r--r-- 1 root root 31276 Apr 15 17:14 net/3c90x.o
[root@botik drivers]# modprobe -t net 3c90x
modprobe: Can't locate module 3c90x which is needed for 3c90x
Then I compressed it back, and it's found, but doesn't load:
[root@botik drivers]# ll net/3c*
-rw-r--r-- 1 root root 4078 Apr 15 17:14 net/3c501.o.gz

It seems Mandrake 8.0 uses a slightly different layout: I found 3c90x.o.gz in
/lib/modules/2.4.3-20mdk/kernel/drivers/net (see above).

Did that (see above), 3c59x loads just fine, 3c90x fails...

lsmod lists 3c59x, seems ok, but Ethernet connection doesn't work...
[root@botik drivers]# lsmod
