Oh... as another point of info, I had initially
installed SuSE using the CDs, which don't have 64-bit support. The 586 version of the kernel and software was loaded, and DHCP was able to grab an IP address, and everything worked (well, except that it was 32-bit and I'd paid for all 64).
When I installed from DVD, I wiped (and re-partitioned) the hard drive, so there's no chance that anything remained. But the 32-bit stuff was working at one point....
