generic 2.2.19 kernel install makes ttyS4 invisible to setserial

Description of problem:
I use the standard 6.2 install with updates from updates.redhat.com with
no changes to the MAKEDEV and setserial rpms.
I replaced the standard 6.2 kernel with a generic 2.2.19 kernel from
kernel.org. Then I tried to reset ttyS4, which my modem uses, using
setserial and setserial says ttyS4 does not exist.
I created ttyS4 using MAKEDEV and reset it with chmod and chgrp to
standard ttyS? settings.
With the standard 6.2 kernel setserial resets ttyS4 every time.
I need the generic kernel to run the MOSIX cluster program.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.delete 2.2.14-5 directory in /lib/modules, and /usr/src if anything is
4.recompile and install kernel
Actual Results: # cd /dev
# ls ttyS4
# setserial ttyS4
# ttyS4: No such device
Expected Results: # setserial ttyS4
I have done this on 2 different computers with the same result.
/dev/lp0 has also become invisible to setserial, and also to printtool.
We don't provide the generic kernel; we provide the one the worked. Closing.
(What was wrong with the Red Hat-provided kernel in the first place?)
The MOSIX cluster program is no longer issued in rpm form. The generic version of MOSIX requires a generic kernel. The rpm kernel
is unacceptable to the generic MOSIX installer.
I tried the generic kernel because I was under the impression that a generic kernel would work equally well.
I looked at Piranha. It does not do what I want done. MOSIX does.
