>Description:
I have problems with my computer.

I configure my own kernel with options VESA and SC_PIXEL_MODE and I can
change the resolution of my screen when I place only one module or RAM on
the motherboard because when I put the second and try to change resolution
using "vidcontrol MODE_XXX" my computer hangs and sometimes when it happens
the internal speaker make a continuous noise.

The problem disappear when I tipe vidcontrol in the machine when it have
only one RAM module.

The problem is not the memory because I have enought modules to change it
and test with the same result, the motherboard (P4C800 E-Deluxe) I know
that it cant be because that computer was working with Windows using
features provided by Dual-Channel DDR and it works...

I will change the motherboard to test it but its impossible to think
that it is the problem.

Sorry, my english is horrible... I hope that can understand my explanation
>How-To-Repeat:
In my situation... to repeat the problem I only must to configure kernel,
compile it and run the machine with 2 modules or RAM... when I use only 1
module I have not problems
>Fix:
The solution is to only use 1 module of RAM... because when you put 2
modules linked in the pair to use Dual-Channel or not linked (using Single-
Channel because the 2 modules are in different place) the computer hangs

To submitter:  Firstly, I'm very sorry that this PR has taken so long

with more recent versions of FreeBSD?  If so, could you try upgrading 
your BIOS and see if the issues remain?
