ifconfig won't find eth0

I can't get my internet connection up. Can anyone help? Here's what's going on:

kernel: 2.4.26
network card: Realtek 8139 (built onto my motherboard)

dmesg seems to show that the card is being identified, but there's an error
about "no socket drivers loaded"

8139too Fast Ethernet driver 0.9.26
eth0: RealTek RTL8139 at 0xe0800000, 00:0a:e6:51:f3:06, IRQ 18
eth0:  Identified 8139 chip type 'RTL-8100B/8139D'
NET4: Linux TCP/IP 1.0 for NET4.0
IP Protocols: ICMP, UDP, TCP, IGMP
IP: routing cache hash table of 4096 buckets, 32Kbytes
TCP: Hash tables configured (established 32768 bind 65536)
NET4: Unix domain sockets 1.0/SMP for Linux NET4.0.
ds: no socket drivers loaded!

ifconfig does not show the eth0 interface, it only shows lo:

lo        Link encap:Local Loopback  
          inet addr:  Mask:
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:4 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0 
          RX bytes:200 (200.0 b)  TX bytes:200 (200.0 b)
cat /proc/pci also seems to find the network card:

  Bus  0, device  14, function  0:
    Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 16).
      IRQ 18.
      Master Capable.  Latency=32.  Min Gnt=32.Max Lat=64.
      I/O at 0xd400 [0xd4ff].
      Non-prefetchable 32 bit memory at 0xdc101000 [0xdc1010ff].
dhcpcd times out.
lsmod doesn't show the 8139too driver, but that's no surprise because I'm not
loading it as a driver - it's compiled into the kernel.

Any ideas are greatly appreciated... I figure if I can get ifconfig to recognize the
card then dhcpcd should work... so I guess that's step one

(Just to rule it out, this card *does* work -- otherwise, I wouldn't be able to make this post )

ifconfig -a to list inactive too
check your network /dhcp) configuration file (depends on distr.)

do (use ip from your subnet)
ifconfig eth0 netmask up
route add default gw <- your gateway here
for debuging.
remember: "man" is your friend...

Well, upgrading to kernel 2.6.7 seems to have worked for me... so I guess all is well.
Still would like to know why 2.4.26 wouldn't work...

Oh well

Thanks for the help

I've noticed in the kernel config that there's an option to include support for "revision c type cards", just below the 8139too support. perhaps that wasn't checked off? The smallest things bring the biggest grief. I think that by checking that off, I couldn't load the module for my last 8139 card. Just a thought. I like closure too.
