The TODO is desperately out of date.  No one cares about 2.4 at all.
These days we don't really allow drivers to have backwards compatability
code so they compile on old kernels.  That stuff has to be stored out of
the main kernel tree.  We also have the compat-wireless and other
similar ways of backporting drivers.

There are still the occasional GFP_DMA without a memtype issue.  I'm not
certain what the fix is for those.  You could probably find them using
Coccinelle.
