So any concern on switch softfp to hard? Meanwhile, what compiler is being used 
for Maemo 5 build? Does it support Neon naturally? 

And as you may know, so far, we had switch compiler to 4.5.0, so seemed it is 
also time to change those flags.

The N900 hardware (Cortex-A8) does support hard float.

However, Maemo 5 builds with the Neon VFP but in soft-fp mode. That is, it uses 
the hardware for manipulating the floating point values, but parameters are 
passed in ARM GP registers.
