Hello,
here is output from dmesg for psmouse.ko

As you can see it takes about 5 seconds to initialize TrackPoint input
device. And about 3 seconds from stage after synaptics export serio
device. I think this is just because of trying to detect device type.
Is there any way how to speed it up? Maybe for synaptics serio devices
try to probe for TPPS/2 at first?

Did you abandon your trusty Dell with ALPS? ;)
Yes, I think we should limit the number of protocols that we probe on
pass-through port to standard PS/2 flavors + TPPS/2 since I have never
seen anything else there.
Thanks.

And If not limiting, at least changing order and preferring TPPS/2.

Umm, that is not something I'll do lightly as it may lead to
regressions: some devices are confused by other's probes and assing even
more psmouse_reset() calls will slow down boot even more.
Thanks.

Ok, then limiting just to TPPS/2 and PS/2 protocols.

Dmitry, do you have some idea how to achieve this?
Modifying psmouse_extensions() function or extending max_proto variable?
