woody, apt/source.lists and pool: where is xfree 86_4.0.2 ?

[mgi@vt.edu]

Last week I installed woody and XFree86_4.0.2 by changing stable to
unstable in the source.list.

Today, I need to reinstall the system and cannot find any of the deb
files for xfree86_4 anymore.

What do I need to put in source.lists to get apt-get and dselect to
download new packages?
