LPM equivalent for ATtiny10?
From the ATtiny4/5/9/10 datasheet, section 5, "Memories", subsection 5.1, "In-System Re-programmable Flash Program Memory":


  Constant tables can be allocated within the entire address space of program memory. Since program memory can
  not be accessed directly, it has been mapped to the data memory. The mapped program memory begins at byte
  address 0x4000 in data memory (see Figure 5-1 on page 15). Although programs are executed starting from
  address 0x000 in program memory it must be addressed starting from 0x4000 when accessed via the data
  memory.


So you will need to add 0x4000 to the address in flash to access the same location via the data bus.
