In general, gpsd should have no effect on whether your GPS can get a fix
or not.  gpsd mostly just decodes the data the GPS sends.

gpsd could be at fault if your new GPS is sending a good lat/lon but
gpsd is not decoding it.  Have you looked at the raw GPS output to see
if it really does have a fix?

We do see that different GPS models have different hardware sensitivities
and new ones of the same brand are occassionally less sensitive than the
older models.  For example the SiRF III's work much better indoors than
the SiRF IV's.

It may be that being a new GPS it has not yet downloaded a full almanac.
Have you tried taking the GPS outside to a good sky view and just let it
sit (powered on) for a few hours?
