I don't know what limon does, but zImage doesn't load at address 0......

If this is really address zero, these instructions are left over
from the last kernel boot.

No.

I don't know. On the PQ-II (8260), the zImage should be loaded at or
above 0x900000, then jump to that address. The code will relocate,
uncompress and start the kernel.
