Have reached the conclusion that WMWiFiRouter version 1.50 was the culprit behind the backlight auto-turning itself off every 30 seconds, not your ROM or anyone else's.
So, updating WMWiFiRouter to version 1.52 (their version of a hotfix) appears to have fixed the backlight issues many of us were having.
At any rate, thanks for looking into the matter, and sorry for giving you grief over this issue...it was never your fault.
Oh, and thanks for the new ROM, going to go download it now
