The development machine on which I'm doing this testing has a VIA 
Apollo Pro+ chipsetted motherboard, Intel PIII-400 processor, so no 
true APIC anyway.  Also, I was using Linux kernel 2.4.20 without APIC 
installed there, either, but just to test (and since upgrading is so 
fun anyway) I upgraded to 2.6.7-rc1 and wound up with essentially same 
problem (module load errors with one PCI configuration, lockups with 
another).

I'm guessing, however, that the i537 that you are using is not an 
i537EP, which is what I have.  I'd suspect that the "i537" that you 
have actually uses an MD3200 chipset on it.  The i537EP has an 
FA82537EP chipset.  Such a small model name change indicates a 
relatively large hardware change, apparently.

Thanks.
