6.0RC1 - enabling synaptics touchpad freezes machine

[Tom.Lislegaard at proact.no]

I try to enable touchpad support on an Acer Travelmate 8104
by setting hw.psm.synaptics_support="1" in loader.conf.

After that any access to psm0 seems to hang the machine solid.
For instance running 'moused -p /dev/psm0' or starting Xorg with
psm0 as mousedevice freezes the machine immediately, and I have
to use the power button to recover.

This is an out-of-the-box 6.0RC1 Generic kernel. The only
other change I've done is to disable acpi, though that doesn't
change anything regarding the touchpad problem.

Is anyone else seeing something similar (and preferably have
a solution)?

Output of dmesg is found below.
