FreeBSD has mapping at zero address feature turned off since 8.0-RC2:

|
|
|
http://security.freebsd.org/advisories/FreeBSD-EN-09:05.null.asc
|
|
|
|
This is required to read EDID data via classical VBE interface (to avoid
|
|
"mmap /dev/mem: Invalid argument" message from libx86). To temporarily
|
|
disable this protection, issue the following command:
|
|
|
|
# sysctl security.bsd.map_at_zero=1
|
|
|
|
To return to secure state:
|
|
|
|
# sysctl security.bsd.map_at_zero=0
