I can't find information about ECC memory support for IBM 6791-KAG
(ECC 133 SDRAM). (It's much cheaper
than pc133). There is nothing about it.
That's all I've got: http://www-307.ibm.com/pc/support/si...IGR-41234.html

In any case I would expect that the ECC/parity bits would be ignored
if the chipset/BIOS doesn't support it. Therefore I'd buy the
unbuffered ECC SDRAM. If it works, then good. If not, then try
snipping off the extra chip(s) with a pair of sidecutters, or cutting
the traces to the ECC/parity data pins.
BTW, AFAICT, an ECC DIMM is identical to a parity DIMM. It's the
chipset that defines the function.
One thing you could try is to buy the ECC/parity DIMM and test it with
Memtest86+. That may at least tell you whether ECC support exists in
the hardware and has been left out of the BIOS. If so, then there may
be a way to modify the appropriate chipset register(s) to enable ECC
support.
