Architecture: x86_64
Machine: amd64
>Description:
        There is a char-device definition for i386 and ia64 named vmnet and 
vmmon.
        A search for theese show up that this is used nowhere in the 
kernel-sources - so no driver
        for the reserved majour-numbers in the architecture dependant ranger 
(below 143) is
        available.
        The names vmnet and vmmon will only show up in "sysctl kern.drivers".
        No kernel configuration ever uses this and it looks like that there is 
no loadable module
        for that too.
        There are empty manual pages (from 2003) that say in the bugs section:
        "jdolecek%NetBSD.org@localhost has not yet written this man page."
        The name sounds like a relict from outdated vmware support approches - 
but I may be wrong here.
>How-To-Repeat:
        Search for vmnet and/or vmmon in the kernel sources. You will get the 
following:

>Fix:
        Eliminate the unused char-device definitions in device-major of i386 
and ia64.
        Eliminate the useless empty man pages for the non-existing drivers in 
/usr/src/share/man/man4.
