Hmm from the 2.6.32 base kernel we get the following but nothing similar
from the Lucid kernel:
[ 9.495785] IBM TrackPoint firmware: 0x0e, buttons: 3/3
[ 9.737128] input: TPPS/2 IBM TrackPoint as
/devices/platform/i8042/serio1/serio2/input/input12
The driver support for that device is enabled by the fragment below:
#ifdef CONFIG_MOUSE_PS2_TRACKPOINT
{
.type = PSMOUSE_TRACKPOINT,
.name = "TPPS/2",
.alias = "trackpoint",
.detect = trackpoint_detect,
},
#endif
And this does appear to be enabled in our kernel:
debian.master/config/config.common.ubuntu:CONFIG_MOUSE_PS2_TRACKPOINT=y
If we compare the two dmesg files in greater details we can see that the
mouse is being found but miss-classified, in the working case:
[ 0.729671] input: Macintosh mouse button emulation as

In the broken case:
[ 0.544008] input: Macintosh mouse button emulation as
/devices/virtual/input/input3
[ 0.602217] serio: i8042 KBD port at 0x60,0x64 irq 1

[ 8.158980] input: PS/2 Generic Mouse as
/devices/platform/i8042/serio1/serio2/input/input12
Now ... why are we doing _that_ I wonder.
