Minor correction. Suspend/resume was around in late 3 and 4, though
the Nomad code in 3 was a bit unstable. It worked well in 4, but was
dependent on APM which was already being replaced by ACPI. By the time
5.2 was actually released, many systems were being shipped without
APM, so could not run FreeBSD. (APM was fairly optional, but ACPI
systems really need ACPI support.) ACPI was one of several things that
forced 5.0 to be released even though RE and everyone running current
knew it had big problems. It i also why 5.0 and 5.1 were clearly
marked as "development" releases not for production.

I really hope to never see a release as ugly as 5. 9.0 may have issues
as did 7.0 and 8.0, but for most, it works quite well. I m happily
running it on a couple of systems.
