No, I mean at "maemo-extras" http://wiki.maemo.org/Extras , don't you use it ?
Specifically at extras-devel.

Alternatively, if you are building your own version, I am attaching the patch, but I haven't tried with latest SVN. It is just touching the ps2 mouse emulation to return absolute coordinates if the guest mouse driver requests it.
You should also disable "autolock" in dosbox.conf for better effect.

The windows side I explained at https://talk.maemo.org/showpost.php?...&postcount=695

You need to put the tablet.drv file in C:\Windows\System , and then edit C:\Windows\System.ini so that the mouse.drv line reads
"mouse.drv=tablet.drv" .

This still works on the PC at least.
I don't remember where tablet.drv comes from, but I either used debug.com to change it from mouse.drv or got it from the windows for pen computing edition.
