Well, your touchpad is using PS/2 so no it's normal you do not have any hidraw
node. The dmesg shows that your touchpad is ps2 only, so there won't be much we
can do in the kernel if the evemu-record. Peter if you can pinpoint where the
jump happens in the evemu-file I might be able to tell if if this is fixable in
the kernel or not.
