I checked it out and you are right. My bad.

The same is also valid for Wheezy.

Anyway, FPU code seems to still be available as an configuration option. Slackware se alternative "huge.s" kernel does come with this option precompiled in:
> CONFIG_MATH_EMULATION=y
ftp://ftp.slackware.org.uk/slackware/slackware-14.0/kernels/huge.s/config

This is an alternative kernel and needs to be specifically chosen during the installation. The default is huge smp (which requires i686 and PAE).
