Laptop Dell Inspiron 5000e UXGA 1600x1200, ATI Rage Mobility 128 M3, XFree86 4.3.0 crash

[Gilles van Ruymbeke <gvr_xfree86_123@xxxxxxxxxxxx>]

Hi,
Please find attached the log file of Xfree86 after the default install of 
Mandrake 9.2.1
Actually I have the same problem with previous versions of Mandrake and 
also Mandrake-move.
I also attached my XF86Config-4 file which after modifications now works, 
see #GvR
The file XF86Config.new.ok is the modified working config file after 
running xf86cfg.
Hope this will help.

My setup:
Laptop Dell Inspiron 5000e UXGA 1600x1200, ATI Rage Mobility 128 M3,
Mandrake 9.2.1, XFree86 4.3.0, Synaptics Touchpad enabled + USB Logitech mouse.

Problems:
1) After a default install, X do not start, see log file, until the config 
file is modified as follow:
        VertRefresh 60 ==> 59-75

2) If any move is done on the touchpad the keyboard do not respond anymore,
and the only way I found to get it back is to start harddrake2 through the 
network !
To solve this: add an 2nd mouse on /dev/psaux assuming the one already used 
by the system is USB:

Section "InputDevice"                   #GvR
    Identifier "Mouse2"                 #GvR
    Driver "mouse"                      #GvR
    Option "Protocol" "auto"            #GvR
    Option "Device" "/dev/psaux"                #GvR
EndSection                              #GvR

Section "ServerLayout"
    InputDevice "Mouse2" "SendCoreEvents"       #GvR
EndSection

3) If any vga mode is used during linux startup, as vga=794 in the lilo.conf,
Videos don't play properly when using totem, xine or mplayer:
The half left of the movie is shown horizontally stretched to fill the full 
window size.
If no vga mode is defined, (see commented line #GvR in my lilo.conf) X 
works fine.

Could you please advise/help me ?

What should I do to get X (re-)initialize properly the chipset even if a 
vga line is used in the lilo.conf ?
How change the console resolution besides the vga line in the lilo.conf ?
What is the vga=xxx to use to get that 1600x1200 resolution ?
Is there any way to get the default install of the next Xfree86 release to 
work on the Dell Inspiron 5000e UXGA ?
Same thing if more than one mouse is present on the system as a TP and a 
USB mouse ?
This even more important for a CD Boot version like Mandrake-move.

Please feel free to ask for any information you would need.
Thanks for your help/support,
Gilles van Ruymbeke
