Whoops, sorry about that! I think the attached one is correct, although I
still get messages about:
Warning (expand_objects): object
/lib/modules/2.4.20-FW20/kernel/net/sched/cls_u32.o for module
cls_u32 has changed since load
which I don't understand.

This is stock Linux 2.4.20 with a whole raft of patches applied:
- UML host skas3
- ebtables and bridge-nf
- iptables IMQ
- iptables patch-o-matic 20030422 (selected patches)
- VLAN MTU patches
- Robert Love's preempt kernel
- LKCD
- ARP antidote
- LVM
- FreeSWAN with 1DES support
- and a few custom patches.
However, none of the files in fs/jbd, fs/ext3 or fs/ext2 have been
modified, they are all dated Nov 28 or earlier.

Hope this helps =)
Cheers, Chris.
