Yes. If you can install >4GB RAM, the CPU+motherboard will use it.

No the limitation is with the CPU, which has 40 physical address lines.
So you use 2^40 bytes of RAM.

What is a 128 MBit chip?

See the recomendations for your motherboard. The motherboard+CPU can use
2GB modules, but some aren't made well and aren't fully to JEDEC spec.
So do some research to find good 2GB DIMM's.
