When you build your kernel, have you modified your Makefile
to have '-ltsp-nolpp' in the EXTRAVERSIONS ?

if so, then your modules should be in "/lib/modules/2.4.18-ltsp-nolpp"

modprobe looks in /proc/version to see the name of the current
kernel. It then uses that to figure out which directory to
get the modules from '/lib/modules/2.4.18.

Eric doesn't build the kernels. I do, and i've provided you with
the ltsp_initrd_kit, which includes the scripts that I use, and the
.config files for my kernels.

Try adding 'INITRD_DBG=1' to your 'append' line for your kernel in
the pxelinux.cfg/default file.

Then, you'll get a shell prompt as soon as the /linuxrc script
starts executing.

You won't have 'ls', but you'll have 'echo', so you can do
things like this:

  cd /lib/modules/2.4.18
  echo *

and it should list any files in that directory.

I think you'll have 'cat' at that point, so you could
cat out the contents of modules.dep.

You can also do this:    cat /proc/version
to see what version of the kernel you are really running.

See what that shows you, and report back.
