 FPA, it doesn't make sense to implement soft-float support (except for
 a few corner cases, which involve no communication with the FPA ABI,
 or you' get a big slowdown with the conversion needed).
 Soft-float support is needed for some other ARM linux distributions
 (as used in the motorola Linux phones, for example), but it is
 irrelevant to the nokia 770.

+"Maemo 2.0 introduces a major binary break due to the adoption of EABI
+toolchain and several API changes requiring porting of all existing
+maemo 1.1 applications to maemo 2.0."
+
+The new version of the firmware for the Nokia 770 uses the ARM EABI.
+It's now compiled with softfloat, not hardfloat.
+
+Empirical reports say that people have seen performance improvements
+of "50 times or more" in their FP code
