Tested on OS X 10.5.8 (GCC 4.2.5), locale en_US.UTF-8:
Inkscape 0.47: 'Exponent' is limited to 128.0
Inkscape 0.48.0: 'Exponent' is limited to 128.0
Inkscape 0.48.1: 'Exponent' is limited to 128.0
Inkscape 0.48+devel r10032: 'Exponent' is limited to 50.0
AFAICT this is a regression in current trunk only.
Note: I don't see the limit 100 in older versions either (it's 128.0 on my system - filter primitive 'Specular Lighting > Exponent'). The 'Specular Lighting > Constant' setting on the other hand is limited to 100.00 in older versions, and 5.00 in current trunk.
