Are you sure that eth0 is coming up at all? Do you see it in the
output of dmesg with 2.4.20? Most likely, if this is a prepackaged
2.4.20 kernel, you forgot to load the network driver module for your
NIC card in /etc/modules (test by 'insmod <name>' the module followed
by 'ifup eth0').

What module is being used? You say you 'insmod' but you did not tell
us what it was you did exactly.

If eth0 is being initialized as indicated by dmesg output, the next
step is to determine if dhcp is working. If you built your own kernel
and are using the ISC dhcp client you may have forgotten to include
the correct network filter options (you will have to search the
archives, but from memory you will need the packet filter). You can
easily test this by running the dhcp client by hand on eth0, it will
print a warning if the kernel options are missing.
