In my quite old laptop there is a synaptics-like touchpad that lies
about its coordinate range. As a result it doesn't work: all its reports
are filtered out as being "out of bounds". This can be remedied by a
set of sysctls to correct this, except these sysctls are also rejected
for being out of (other) bounds. The patch below "fixes" this in a hacky
way (by removing those bound checks).
I corresponded with blymn@ when 10 was branched and he wanted to make a
proper fix, but apparently that didn't make it into 10.0.
It's not a showstopper since I can easily build a custom kernel with
this patch, but for 10.1 it would be nice to have.
