installed new kernel, but lost internal network

Hi,
I am doing masquarading using my Debian machine running Sarge. Earlier I was running the default kernel that comes with Woody (2.4.18-bf14 or something). Today I upgraded to the new kernel: /var/log# apt-get -u install kernel-image-2.4.22-1-686 kernel-doc-2.4.22 kernel-headers-2.4.22-1 kernel-pcmcia-modules-2.4.22-1-686 pcmcia-cs hotplug usbutils fxload hotplug-utils
And after this, I lost one of the NICs. I have two NICs, one is 192.168.0.1 connected to the ADSL moden, and the other is 192.168.0.2 connected to the internal LAN. So when I booted into the new kernel, the second NIC RLT8139 was not detected. But when I did pppoeconf, it listed only 1 NIC and asked if I had more which were not detected. I said Yes, and it hen allowed me to install the module for the RLT NIC. And after that it reported 2 NICs fine.
So after configuring ppp0, I could browse the net, but my internal LAN machine can't. I can't even ping that machine. I am running the same iptables rules as before. Here is what I get: 
/var/log# ping 192.168.0.10
PING 192.168.0.10 (192.168.0.10): 56 data bytes
ping: sendto: Operation not permitted
ping: wrote 192.168.0.10 64 chars, ret=-1
ping: sendto: Operation not permitted
ping: wrote 192.168.0.10 64 chars, ret=-1

--- 192.168.0.10 ping statistics ---
2 packets transmitted, 0 packets received, 100% packet loss


I get this evenif I do "/etc/initd/iptables clear".



Here is my interfaces file:
/etc/network# more interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

# The loopback interface
auto lo
iface lo inet loopback
# The first network card - this entry was created during the Debian installatio 
n
# (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
        address 192.168.0.1
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        #gateway 192.168.0.0
auto eth1
iface eth1 inet static
        address 192.168.0.2
        netmask 255.255.255.0
        network 192.168.0.0
        broadcast 192.168.0.255
        #gateway 192.168.0.2
Any idea what could have gone wrong during installation of thsi new kernel? More information is below. 

Thanks,
->HS
