I have found: a temporary solution.
----------------------
I load LiveCD ubuntu 10.04 release 29/04/2010
with MONITOR turning OFF.
After it stop (no blinking on any led) I turn on the monitor,
choose "Try Ubuntu without installation"
>>>> then imediatly turn off MONITOR.
WAIT TILL all LED stop blinking, which mean fully loaded.
Turn on the monitor, then I got high resolution.
-------------------
But After I order installation and reboot from hard disk,
Lucid fail to load in higher resolution than 960 X 600.

I did tried many times with,
turning off the MONITOR at the same as CPU-Box computer.
I waited till I think it fully boot into Ubuntu, then turn on the monitor.
It failed.
---------------------------------------- 
Then I finally tried and successfully get back higher resolution by

1. I have successfully fool Fedora 12 to load into 1152 x 864 (4:3)
by
       1.1 turn off computer, turn monitor off too, and turn on just computer.
       1.2 Once, a few minutes, guess that you are at the Grub menu, turn on 
the monitor, and l pick to boot into Fedora 12 ,
        >>> after press enter, immediately turn off monitor.
       1.3  I let Fedora 12 to load completely (while leaving MONITOR OFF)
       1.4  Turn on monitor and I got 1024 x 768 or 1152 x 864, I cannot 
remember (just so happy) but finally I set it to 1152 x 864.
        So it is ok with high resolution until now.

2. I fool Ubuntu 10.04 (30/04/2010 -fresh re-install from LiveCD), and no 
update by 
       2.1 After successfully fool Fedora 12 for high resolution, choose 
restart, (not shutdown), and do not turn off the MONITOR.
       2.2 wait till it reboot into grub menu and choose to boot into Ubuntu 
Lucid 
       2.3 Yes got 1152 x 864.

I have include the same kinds of files

sysinfo1 > from sysinfo program
lsmod, lshwCdisplay, lspciVVNN, lspci, Xorg.0.log, Xversion
---------------but I did not change any thing from standard installation ----
I include these two files for comparison to the previous post.

grub.cfg and modules
===============================

Conclusion for the moment. 
Lucid did work ok with SIS for high resolution temporary.
but detection of the Packard Bell monitor made it falled back to choose lower 
resolution for our Lucid Hard disk installed version.

Fedora can be fool with the above procedure but not Lucid.

the help "is need" to make Lucid stupid like Fedora 12
So I can or may be someone else too ?? , can use SIS for higher resolution 
until the fixed arrive.

Or the problems lies on the Packard Bell monitor ??
I will be trying with other monitor and will let you know.

I am working to promote UBUNTU not Fedora, so please help.
