The gdesklet is on crack actually, and those values don't really come
from anywhere and break with different cards. NM is using the values
_directly_ from the driver, the same values you see in 'iwconfig'. If
the driver's idea of quality and max quality is off, then the solution
is to fix the driver, not work around it with code like gdesklet does
that doesn't make any sense for all cards...
