Our experience is that froyo CAN support mouse with no/little extra effort.
I recalled that I spent a little time to work through the path and might
have some small fixes, then it worked.
Please give us a tip ^_^
Sorry for the long delay. I would like to recommend this:
http://blog.csdn.net/myarrow/article/details/7091061
for understanding of android input system.
I have looked at the old froyo code, no bug fixes are needed for the
mouse to work. So just try to understand the input flow, find out what
is wrong.
e.g. does getevent(run it in adb shell) output something when you move
the mouse? if so, does EventHub get the event? (enable or add some
debugging information in frameworks/base/services/input for ics, in
frameworks/base/libs/ui, EventHub.cpp, InputReader.cpp,
InputDispatcher.cpp etc.)
ICS repository for loongson3 laptop is now uploaded to
github.com/foxsen, the input system need the following patch(I don't see
why it will not cause problem for other platform...)

The array size will be zero for relBitmask etc. with original code.
To get all code:
mkdir loongson-ics
cd loongson-ics
repo init --repo-url=git://github.com/foxsen/repo.git
--repo-branch=stable -u git://github.com/foxsen/manifests.git -b
loongson-ics-r0 -m loongson-ics-r0.xml
repo sync
Will check the code when have time。
For 4.0, there is a bug prevent a mouse being recognized as CURSOR
device，will post the code（together with the other fixes） to my github
later.
BTW:
I have finally got some free time in last weekend to continue. Now
android ics for loongson is in a good shape for LS3 laptop：
opengl, alsa sound, mouse/keyboard, wifi, fake sdcard (to make lots of
apps happy), some mips apk from Junzheng nova system including QQ/金山
wps etc. partly works.
With some more work, lots of apps are hopefully to work with decent
performance:0
Nice news. If someday I can have a LS3 laptop, I will be glad to join you.
