hrm with ruby if you are expecting a number in that field and try to
parse it, the units will be lost:
Unknown-00-1f-5b-ec-f0-9b:~ shaunmcdonald$ ruby -v
ruby 1.8.6 (2008-03-03 patchlevel 114) [universal-darwin9.0]
Unknown-00-1f-5b-ec-f0-9b:~ shaunmcdonald$ irb
>> "30mph".to_i
=> 30

Now there is a reason from a programmers point of view why units
should be left out of the value.
(I now better run an hide while someone comes up with a way to parse
that string into an object containing the speed and the units).
