PS/2 mouse not working with USB legacy option enabled in Kernel 2.6

["Kushal Koolwal" <kushalkoolwal@hotmail.com>]

Hi,

I have been using Debian 3.1 (Sarge) with kernel 2.6.8-2-386 on my Pentium M 
system. A couple of days ago I noticed that my PS/2 mouse won't work when I 
enable the 'Legacy USB' option in my BIOS setting. If I disable the 'Legacy 
USB' option, my PS/2 mouse works fine along with USB mouse. My USB mouse 
works fine in both the situation i.e. when the 'Legacy USB' is 
enable/disable I have tried the workarounds like:

psmouse.proto=imps and i8042.nomux as kernel boot parameters but it didn;t 
help.

I did a lot of researching over the Internet and then I found that it is 
because in Kernel 2.6 they have moved the drivers into the kernel space from 
the user space. Unfortunately I was not able to find a solution how to get 
the PS/2 mouse working with USB Legacy option enabled in the BIOS.

Also, I have tried the following link but I was not successful.
http://www.informatik.uni-freiburg.de/~danlee/fun/psaux/

Also the following links reports that it is a bug but apparently no clear 
solution has been given.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=120859
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=137691

Any help will be greatly appreciated.

I will be glad to post any diagnostic output like:
cat /proc/bus/input/devices
lspci -xvvv
dmidecode
etc....
