I asked HTC about white spots and the new Diamond and Touch Pro toay:

"@htc I'm hoping the vibration motor won't cause LCD spots on the Touch Pro, like it does on Mogul."
"@frejos play teeter on the pro or diamond and you'll see the vibration motor has no negative effect on the display. plus you'll have fun too"

Sounds like they've even done testing specifically for the issue, which I think is good news.
