I've got LinuxPPC kernel version 2.1.24 (pmac) installed
on my 8500/120 on a Jaz disk.
I'd like to get it working with my RoadRunner cable modem.
I understand there is a problem with 2.1.xx kernels and
dhcpcd, and from some digging I have heard of a patch that
is supposed to fix this.  However, I am not sure this is
the problem.  
Here are my symptoms, someone please give me a hint:

when I try to run dhcpcd or rrdhcpcd from the command line
this is what I get:

rrdhcpcd forgot to specify route netmask
assigned IP address: 204.210.235.118  (or whatever it gives me)
assigned subnetmask:     255.255.255.0
rrdhcpcd forgot to specify route netmask
ioctl SIOCADDRT     (ifConfig):Invalid argument

After this, I am able to ping the router and myself just
fine, but I get the error message "network unreachable"
when I try to ping the dce-server or anything else outside of
the netmask (204.210.235.xxx)
This sucks, b/c I have to be able to get to the dce-server to
run rrclientd, which puts in my password.

Ive got     /etc/dhcpc/resolv.conf setup
and a link to it in /etc Here's what it looks like:
domain columbus.rr.com
nameserver 204.210.252.18

I also have /etc/sysconfig/setwork-scripts/ifcfg-eth0 setup like
this:

DEVICE=eth0
IPADDR=
NETMASK=255.255.255.0
NETWORK=
BROADCAST=255.255.255.255
ONBOOT=yes
BOOTPROTO=dhcp

Also, I tried changing my netmask to 255.255.0.0 but that
didn't work.

I read a couple things about people having similiar problems
but they were able to manually add a route, how do I do that?
I'm guessing something like
route add -blah something ?

This seems like this ought to have a simple fix, if I'm able to
ping the router.

Please help !!
