Pad the kernel file to get its size a multiple of 4 bytes ;-)
Some old boot PROMs seem to get tftp data by block of 4 bytes.
I ran into troubles many times before someone posted in this list discovered
this problem (many thanks to him).
Now every kernel provided by the boot-floppies package is processed through the
next statements:
size=`ls -l kernel | awk '{print $5}'`
rem=`expr \( 4 - $size % 4 \) % 4`
dd if=/dev/zero bs=1 count=$rem >> kernel
Hope this helps you.
