I believe that the LED addresses are 0xC0220118 and 0x022011C however I have not been successful in testing this.

i would guess, both being digic-iv and otherwise closer to each other, that the sx120 port http://chdk.wikia.com/wiki/SX120IS would be a better reference to guess at things from instead of the sx110.
<tangent> personally i can't believe they release this update a year or less after the last one! i wonder if the optical quality is improved any to go along with the higher zoom and MP... </tangent>

For firmware 1.01C the d4b key is located at 0x7E3618 and the d4b IV at 0x3EDA1B.
(The actual key/IV pair is the same as for SD4500 and possibly S95)
These together with a PID of 0x3211 encrypt successfully the PS.FI2 .

I check d4b key of SX130, SD4500 and S95 and key is the same, but
are You sure about offset for d4b IV key?

I check with d4b IV key for SD4500 and it is not the same key ( d4b IV key offset for SD4500 is 0x43B71C, confirmed).

I cant find information about d4b IV key offset for S95.

Please check d4b IV key offset.

UPDATE

d4b IV key offset is wrong

Correct info:
For firmware 1.01C the d4b key is located at 0x7E3618 and the d4b IV at 0x3EDA0C (length 16 bytes/32 hex values)
(The actual key/IV pair is the confirmed same as for SD4500 and S95).
