I deliberately compiled those out as modules, and when booting with
init=/bin/bash the agpgart and ati_agp aren't loaded.  (if they're
loaded, it makes no difference).

Would the filesystem really make a difference to whether it can or can't
come back?

Doesn't work either.  I got swsusp2 to work, but that has to shut down X
and unload all the modules otherwise it won't resume; and that takes
longer than a simple shutdown and boot -- so I abandoned it.  Plus it
scared me -- too much pretty :)
