Ok, these are the differences when no motion:

0x07:
You: 28
Me: 00

0x08:
You: 88
Me: 00

0x09:
You: 6A
Me: 00

0x0A:
You: 2A
Me: 00

0x0C:
You: 00
Me: 4E

0x0B:
You: 61
Me: 20

0x0E:
You: 0F
Me: 5D

0x0D:
You: A0
Me: C0

0x0F:
You: 38
Me: 12

0x10:
You: 08
Me: 00

0x1B:
You: 0F
Me: 5D

0x1A:
You: A0
Me: C0

0x25:
You: 00
Me: EF

0x26:
You: 00
Me: BE

0x2e:
You: 1F
Me: 10

I will look into these some more, and see if it helps changing to your values on those that I can write to. If you see anything obvious, please tell me. Btw, shouldn't you have BE and EF on 0x26 and 0x25 too? That indicates that the SROM is fine... although I see your SROM_ID is 0x91 (address 0x2a)...
