I can confirm that, however:

The maemo folks also moved to a cpu that is 50% faster in general and at least 10 times
faster in floating point ops because it has an actual FPU *and* abondoned development for
the old FPU-less hardware.
Cairo has indeed gotten *a lot* faster, but citing maemo in that context is misleading and
should be avoided.
 the n800 has an TI OMAP 2420 (330MHz, arm1136 based, armv6 instruction set), the n770
a TI OMAP 1710 (250MHz, arm926 based, armv5te instruction set), the neo a Samsung s3c2410
(266MHz, arm920t based, armv4t instruction set).
