Summary: check_disk reports incorrect disk free with neg space on BSD

Initial Comment:
With check_disk running on FreeBSD 5-STABLE, when a
disk has negative free space remaining, the amount of
free space goes hugely positive:
DISK CRITICAL - free space: /usr 36028797018963968 MB
(1191472380510208%):

Here's a df from the time:
/dev/ad4s1g          3096462   2989082  -140336   105%
   /usr

hi,

um, i just have to ask.  how do you have negative free space?  

some other information that would be helpful:
- is check_disk using the df command or internal disk space
routines?
- if df, what df command syntax is check_disk using?
- what version of the plugins are you using?

i believe that the plugin is making an assumption that the
amount of disk space available is unsigned, because, er...
well i'd never heard of negative disk space, anyway :)
