Anyone remember 32 bit/33 MHz PCI slot SSL accelerator cards? As I recall openbsd had kernel driver support for several

Yes. I still have one. I used it in a Soekris 486-class machine running OpenBSD for many, many years. I stopped using the Soekris when they dropped driver support for the accelerator. I think i386 support might be gone now too. Cool little card; I think I might still have it in a drawer somewhere.
