If I put the echo command inside /etc/gdm/PostLogin/Default , it is ignored in karmic (wasn't in jaunty). I can make it stick by putting it in /etc/rc.local (but with the provisos noted by the posts above).
With mtrr correctly setup, their is a very slight improvement in flash performance, so it appears to be doing something. I am not using an intel gpu - I have an nVidia one.
Although I understand this issue is fixed in karmic, I found that if I issue (under karmic)
cat /proc/mtrr
I see the output shows that mtrr is not set up.
I can fix it for my gpu card by issuing a

My /boot/config- 2.6.31- 15-generic contains
CONFIG_MTRR=y MTRR_SANITIZER= y MTRR_SANITIZER_ ENABLE_ DEFAULT= 0 MTRR_SANITIZER_ SPARE_REG_ NR_DEFAULT= 1

CONFIG_X86_PAT=y
So does this mean I don't need to set up mtrr in karmic? And it is safe to ignore the wrong setup reported by cat /proc/mtrr ?
