This, mostly in order:
- Adds a trademark attribution for NetBSD
- Makes the spelling of DragonFly BSD consistent
- Mention x86-64 as a common non-FreeBSD name for the amd64 platform
- Fix several grammar and spelling issues
- Mention that SMP support is enabled in the default kernel
- Mention the sysv modules are default, but also available as modules
- Default to "xterm" not "cons25", note that <9 uses "cons25"
- Move one paragraph around so that "This" refers to the correct thing
- Replace a reference that still existed to UserConfig (!)
- Remove reference to the defunct "mbone" ports category
- Remove derogatory comment about Windows, untrue for ~13 years
