fujitsu pt510 ( again ) and touchscreen

Hi all;

I now have Linux running happily on the 510 with pcmcia and X running happily.

However I am having little luck getting any infomation from the touchscreen. I have tried various X11 drivers ( from linuxslate.org andfujitsu b112 drivers ) as well as kernel modules for different types of ps2 mice.

Im not sure if the touchscreen is on a ttyS or /dev/psaux, the kernel reports nothing. I have been told ( unreliably however ) thats its a ps2 port on irq 12. Catting these various devices also produces nothing.

Im looking for some pointers on how to begin reverse enginneeing the touchscreen and actually getting some data from it.

dmidecode gives me nothing as does lspci ( the machine does not have pci ).

Any advice, greatly appreciated;
