Lapis, MR45V200A (8 pin DIP, 2Mb). About $7-8 each at Mouser.
I finally got a driver to work, based on other SPI memory (battery-backed). I was hoping that I could find some Propeller code to work with, but ended up doing quite a bit of reading from other platforms.
The key appears to be that you must do a write enable before a write, and that you must raise CS# after the write enable command (can't do the write enable and write in the same CS# lowering).
