conflicting memory types in system logs

[Halim Issa]

Hello,

On X.Org X Server 1.5.3 with the Intel 2.5.1 driver on a Lenovo X200 laptop, I 
get quite a few error messages output in /var/log/messages where the kernel 
complains about conflicting memory types. Is this just warnings, or something 
to be taken seriously? If the latter, is it due to a config error on my part, 
or a version mismatch or bug somewhere? 

System information included at bottom.

Thanks in advance for any insight.
