you should probably use the serial mouse example (mouser) as a starting point, way less crud in it that i8042prt. i would suggest creat a HID miniport (the latest WDK has a great HID miniport example in KMDF). this way you just morpth the data into HID and HIDclass takes care of enumerating a mouse and you get to use the built in mouse drivers.
what aobut just having a user mode application that reads teh data and then calls SendInput instead? much simpler than writing a driver. will any other application consume this data that is being turned into a mouse?

Interesting, ok, thanks, I'll take a look at that now. (I'll be
wondering how much of the code in the i8042prt example is likely
reusable for what I'm trying to do...)

You need:
1) to install your device as Mouse class in the INF file
2) to write the driver as mouse port driver - look at i8042prt DDK sample
The mouse port driver should handle the "internal mouse connect" IOCTL and
then call the upper driver's routine with the array of MOUSE_INPUT_DATA
structures.
