Its clear you're right.

Yes, it is 2.4.22-1.2129.nptl. The kernel is taken straight from the binary
kernel RPM... I install it into the root filesystem and then copy it and some
modules over into the initrd filesystem.
This is my linuxrc modified from the Fedora one:

I used mkfs.ext3 to creat the filesystem, so I did not perform this
transformation action. I am able to mount the resulting filesystem as ext3
via loopback on my laptop, for example.

Having the following generated into /etc/fstab (on both the initrd and root
filesystems, just in case):
/dev/nd0 / ext3 defaults
none /dev/pts devpts gid=5,mode=620 0 0
gets me the following from the /etc/rc.sysinit
Setting hostname localhost: [OK}
Checking root filesystem
/dev/nd0 is mounted. e2fsck: Cannot continue, aborting.
[FAILED]
then it drops to a repair shell.

No doubt there is some stupid thing I am doing... as usual I am operating at
or beyond what I know how to do :-) its the only way to learn new things...
but even so this is being quite painful...
