xf86EnableIO: Failed to open /dev/io for extended I/O

[Trance Kat]

Hi everyone,
My name is Alex, and I have been wrestling with a new installation of 
FreeBSD.  I want to get X Windows running, but I keep getting the error:

xf86EnableIO: Failed to open /dev/io for extended I/O

whenever I run X -configure

I checked /dev/io and it is there.  I looked in the kernel and I do have 
"device    io" there as well.  I am running FreeBSD 5.4-RELEASE. 
/usr/src/sys/i386/compile/GENERIC

Thanks in advance,
Alex
