Ok, I was wrong about the kernel oops, it was for another driver that I
had not turned off. {which has now been reported seporately}

I was also wrong about it acting as if the button was always pressed.
It's just VERY sensitive.
I need to completely re-install my machine now to test it outside of
gpm.  I hosed the system in a futile bid to have a prototype X driver
work instead.

"Kevin K" has replied back saying that the Panasonic Toughbooks also
should use this driver. I've asked him if he would like to test a kernel
for one or a couple since his fix was in the 2.4 port.  If so I'd like
to throw all the additions into a patch and submit it all in one pass..

I added the following to drivers/input/mouse/lifebook.c
        {
                .ident = "FLORA-ie 55mi",
                .matches = {
                        DMI_MATCH(DMI_PRODUCT_NAME, "FLORA-ie 55mi"),
                },
        },

It scrolled oopses for a little while then booted normally.
gpmd using /dev/mouse is taking input from the touchscreen. kind of....

If I move up or down on the screen it moves the cursor like a mouse
would, but it acts like the button is always pressed.


I'm happy that it accepts data at all but concerned about the oops 
scroll...  There is so much that it is pushed out of the dmesg log, and 
the kernel scrollback log.  I have no way of recording it {I can't
soldier 
down a pin header for serial}

Any ideas?
