Would it be possible that your kernel partition is smaller than on other devices? I believe that even on MTD there is some flash filesystem that removes damaged flash blocks from use, maybe your kernel partition has been reduced in size?
Could be, I suspect the flash is damaged, it kind of makes sense now with the issues I've had previously with lost data and settings. How do I see the size of the kernel MTD partition? df shows me:

~ # df -h

Here's the output from sfdisk:

Should I repartition it? I'd have to say I've never done that but there's a thread on the topic here that looks helpful:
