"That's what I used to think, til Jon Ward put me right..."

You know, I thought I remembered reading something about that and went about searching Keil's site for it. I guess I was not patient enough or was not using the right search terms. Thanks for completing my half-hearted search for me :-)

Alas, I now see (again) why that technique is not applicable for me for the time being -- it requires PK51 and I'm a DK51 user. I think that even if I had PK51, personally I would still not use it, since as I have noted before, I'm a multiplatform kind of guy and the C51 facility would not port well :-(
