Subjectmtrr: base(0xf8000000) is not aligned on a size(0x180000) boundary
I get this message on boot with kernel 2.4.9 on a Dell Optiplex GX110 
running redhat 7.0 with X upgraded to 4.0.3-5 with rpms from rh 7.1
(i810 chipset) This occurs during X startup.

here is the device section from XF86Config-4

Section "Device"
Identifier "Intel Corporation|82810E CGC [Chipset Gr"
Driver "i810"
BoardName "Unknown"
VideoRam 16384
EndSection

my search for answers using mtrr 2.4 i810 turns up nothing of interest
so maybe this is a new problem?


please advise

thanks!
