No, the Raspberry Pi version will not use the hardware floating point unit for the base F17 system, its based on the ARMv5tel flavour. F-17 on ARM is only available in two flavours: Fedora 17 for ARMv7hl (Optimized for Beagle, Panda, Trimslice, Efika and other ARMv7 devices) using hardware floating point and the hard ABI Fedora 17 for ARMv5tel (For use with legacy ARMv5 devices such as the Raspberry Pi, Guruplug and Dreamplug) using soft-float and the softfp ABI. On the Raspberry Pi it is possible to utilize the fast Broadcom GPU using the OpenGL ES, OpenVG and OpenMAX API and you can pass -mtune=arm1176jzf-s -mfpu=vfp -mfloat-abi=softfp to GCC to make it use the hardware floating point unit in your own software.
