Find a newer date code, AT89C51RD2, and try that

it is just about impossible to find these. I am willing to bet that a newer version of the same chip will probably work.

Toggle a pin and connect to SS, in case that matters

I did try that, I got nothing from the Logic analyzer. I have disabled SS in the SPI initialization in the above code.

Try other modes, in case your devices have a issue not in the errata

Well, I believe that the datasheet is wrong. I just thought someone would know for sure.
I wanted to use (get rid of) the RD2's I have here. They are working perfectly (except for the SPI) which I believe is not present in the version I have.
My bit-bang routines are working (using the same pins the hardware SPI uses).

I am doing a sound project using a vs1011e, sending a couple of very small MP3 files to the vs1011e using SPI. It is working using the bit-bang method at the moment.
