I'm a bit puzzled. I have a 32mb TT One XL, with a 2GB SD card.
I have tried 9.510 , 9.500 and 9.485 , but when I suspend the TT, it will never wake up.
I have to remove and re-insert the SD-card to make it power up again.
With the (official) 8.010 the suspend works just fine.
Also, I've seen other people reporting that NC 9.x works fine on the One XL.
So ...
