problem with acpi and touchpad

[dawnshade]

Hello, all.

Recently i find strange problem with acer tm 4151LMi laptop.
If i configured acpi (unfortunaly with _disabled_ device apic) FreeBSD 6.0RC1 
cannot detect touchpad (with disabled acpi all fine, detected as psm0), but 
psm0 present in sysctl -a | grep psm:
