We've got preliminary entry in the FAQ.  That entry is also referenced by the
prototype gcc-2.95 features page as well as the prototype gcc-2.95 caveats
page.

I hope to improve the faq entry before the actual release.  In particular we
want to include a better explanation of the generic problem (along with a
code sample?) as well as various options one could use to fix the code.

Then we just mention the Linux kernel as an example of a package which is known
to have this particular problem.

This is basically what we did with the asm clobbers information.  We've got a
generic entry which describes the problem and it references a Linux kernel
specific entry.
