have a look at http://www.heise.de/ct/english/99/05/news1/ (English) and
http://www.heise.de/newsticker/data/cp-22.02.99-000/ (German; different
text).
Additionally, the c't people mentioned in a recent issue (#24, IIRC) that
they wrote a quite simple program which allowed to re-enable the PSN after
some wake-up from ACPI mode, I think. They don't want to publish the
source code (yet), but would give it to some institution (a committee of
the European parliament?) who want to do something against the PSN or
Intel in general.
IMO disabling the PSN unconditionally at boot time is the best thing Linux
can do with it.
Besides, when I look at the severe bugs mentioned in the specification
updates, downloadable from
http://developer.intel.com/design/PentiumIII/specupdt/, I wonder how any
of these P-III processors could ever work reasonably. ;-)
