Maybe I was somehow insufficiently clear:  What _specifically_ about a
card you recognise as having a pair of Silicon Image 3112A chips and an
Intel GC80303 RISC chip says "ICP Vortex" to you?

My point was:  Here's a family of cards (SRCS14L, SRCS16, and SRCS28X)
whose identifiable major chips are (1) a SiI3112A chip for each channel
pair, and (2) one of several Intel RISC CPUs.  The available
documentation doesn't disclose the nature of any _other_ significant
circuitry.

I thus infer that there actually _is_ other significant circuitry --
that determines the host-facing programming interface, and is ICP
Vortex-compatible -- but that the information on the Web doesn't discuss
it.  Therefore:  Sucks to be me.  Moreover:  The standard "identify the
significant chipset, then find a driver" conceptual model we've gotten
used to won't always work well.
