Technically, you can debug your real machine kernel using serial (aka com) port, but I do not think you need to do that. When your kernel panics, it takes your to ddb, right?
You got "uvm_fault page fault trap": it means kernel tries to access some invalid memory address. It happens in "ihidev_intr" (HID-over-i2c driver) at offset 0x18a. This address is stored in registry, that is why Mike Larkin aksed you to do "show reg": get registers values, and send them to list. So, there is some bug in ihidev_intr driver, you need to post whole text + "show reg" output to bugs@ along with your laptop name.
