when you boot to the default kernel, do an lsmod and see what all
modules are installed at the time.  This will give you a hint about what
is needed.   I can't remember everything right now, I'll have to check
if you still can't get it.

yeh, its common... 
in /etc/modules.conf add
alias char-major-# off
if you want to ignore the message.  Otherwise we will need to know what
the # is to see what driver it it looking for.

MTRR (Memory Type Range Register) control
linux/Documentation/mtrr.txt

it included under the processor type and features part of the kernel
config.  I have not used it or had need for it.  Check out the above
mentioned doc.
