If there's a resistor near the HP Lisa chip, it's a rev.2b motherboard, and it's compatible with Indivision AGA 1200, just like all other A1200 motherboards are compatible.
The sockets of the first batch of flickerfixers were only filed down on the spot where this resistor is near. Since HP Lisa chips seem to have a wide variation in height, the second production run was already changed, and sockets were lowered 0,2mm total with power tools.
For the A4000d/CD32 version, we did this prior to production. I took pictures of the tools we've built/used to make the sockets fit perfectly:
