I'm not sure, but have you checked, whether you have installed the
gdal version matches to the gdal-extensions. I remember that I
installed a newer gdal, lets say 1.8.x and had similar problems with
an older geoserver/geotools release. Which version of geoserver do you
have installed?
In addition have a look at geoserver gdal docs :
http://docs.geoserver.org/latest/en/user/data/gdal.html
and check out the geosolutions blog :
