I have Frankenpad 601 that has 2x4g ddr2 800mhz ram, however under Linux

lshw -short -C memory

is showing

/0/2b/0                      memory      4GiB SODIMM DDR2 Synchronous 667 MHz (1.5 ns)
/0/2b/1                      memory      4GiB SODIMM DDR2 Synchronous 667 MHz (1.5 ns)

I know that this might not be that important, but just wondering if the RAM have wrong sticker or a bios limitation or the limitation of the PM965 chip?

Its probably a pm965 limitation. I doubt it makes a significant difference in speed. It's not like a TP755C where 70 vs 60ns ram was a significant.

The memory controller on the Intel 965 Mobile chipset is limited to DDR 667 speed.
