Hah!  Sounds like just what is needed!

So in the OP's case, it seems that installing Debian with a kernel that
emulates the missing instructions, is all it takes to get a working
system, and then you can:
- tweak /etc/dpkg/buildflags.conf to tell the
  compiler to optimize for the armv4l architecture
- use "apt-get -b source <packages>" to rebuild the
  performance-sensitive packages with those flags.
- then I guess you'd use dpkg to actually install those packages.

Hmm... I guess you'd still suffer from performance problems when your
locally-compiled packages get updated by "apt-get upgrade" and hence
replacing your tuned packages with the stock precompiled ones.
So I guess for the sun to shine we'd want some way to flag some packages
as "always install from source" or something like that.
