After some expariment I have found the way to made working kernel.  I
replaced 1.4.1's fp code to 1.4's one.

I made the kernel by following steps.

(1) Extract 1.4.1 source code.
(2) Make config binary in usr.sbin directory.
(3) Copy and modify GENERIC config file.
    - Enable sbc0 driver instead of ncrscsi0 driver.
    - Remove some scsi device ( exactly ch*, se*, and ss* ).
    - Remove NUBUS video card related lines macvid*, grf*.
(4) Copy arch/m68k/fp* directry from 1.4 source tree.
(5) Run config(by step 2's binary), make depend and make.

On this kernel, apache and ps-command seems to work fine.

But the kernel, I think, is not stable.

Last week, I decided to exchange IIvi in my office and Quadra 650 in
my home.  So I can go arround the problem if it will be not resolved.

Thank you.
