There is already an exception in dump_memory() for ixus65/sd630, but it is the same for sd1000 (that's why all addresses are shifted by 0x1900 in memory dumps...):
core/main.c:45,dump_memory
-#ifdef CAMERA_ixus65_sd630 // Zero is not readable on ixus65!
+#if defined(CAMERA_ixus65_sd630) || defined(CAMERA_ixus70_sd1000) // Zero is not readable!
It is probable that all ixus/sd cameras have this problem (at least), people who own such cameras should try to create a ram dump and check whether its size is exactly 32MB (33 554 432 bytes) or 6400 bytes are missing...
