Question [Q] Improved Refresh-Rate on 2.1?

Per the Nookie Froyo thread they have a suggestion to increase the refresh rate to 68000 to stop/reduce flicker.

I noticed a similar flicker on "stock" 2.1 and checked /sys/devices/omapdss/display0/timings only to find out it is also set at 48000. I increased it to 68000, but it is reset after each reboot.

What is the proper refresh rate? Anyone else notice a flicker on the stock ROM?

I used the following from the thread I linked.
Code:
Select Code
adb shell echo 68000,1024/70/200/40,600/10/11/10 > /sys/devices/omapdss/display0/timings

at the end of the clrbootcount.sh text to have it run that command to fix the refresh and make it stick?

I did this (as I posted in the nook flicker thread):

I did a CAT on immediately after, and it had defaulted instead to 66461 instead of 68000 (maximum rate for the chip?)

Of course it also cleared upon reboot. Should I have seen a flicker improvement right away?
