Can the N810 benefit from a Linux EABI ARM Kernel?
 
With EABI processing floating point operations in Software is much faster.

So when we exchance the old Linux Kernel with an EABI one on the Maemo plattform (f.e. Diablo) then the N810 should be faster for typical FPU stuff.

IIRC Diablo used soft-float rather than an FPA illegal instruction handler (Debian is just rather slow with adopting modern practices, when it comes to ARM in particular).

EABI also changes other parts of the calling conventions though iirc, which means that the closed source kernel drivers won't work any more if you do recompile the kernel.

Maemo4 is ARM EABI

Stskeeps, what was the exact configuration related to ARM capabilities within maemo 4?

Usually ARM distributions run in configuration that can work on different types arm processors. E.g. devices with hard fpu, may still use software fpu, or exception based one.
