>Description:
XFree86 4.1.0 compiled from xsrc does not use aperture driver pkg.
The checkDevMem prtocess does not probe /dev/xf86.
In 4.0.3 xsrc probes /dev/xf86 as follows.

before (4.0.3)
>How-To-Repeat:
Install pkgsrc/misc/aperture and add the following line to the /etc/lkm.conf,

/usr/pkg/lkm/xf86.o     -       -       /usr/pkg/lkm/xf86_mod_install   xf86    
AFTERMOUNT

and boot from the kernel without INSECURE option.

You should use a graphic board which require the linear access to the display
memory such as the Matrox G200 (I use this one).

>Fix:
Unfortunately, I don't understand what is wrong...

>Release-Note:
>Audit-Trail:
>Unformatted:
 >(II) checkDevMem: using aperture driver /dev/xf86
 after (4.1.0)
 >(WW) checkDevMem: failed to open /dev/mem (Operation not permitted)
 
 Then X cannot work.
