I agree that the product seems niche. There's practically nothing on
their website on the marketing side - from searching around the details
are pretty much limited to the support pages. I can't really speak to
future stuff like an AST2700-based design though, who knows.

A couple of numbers turned up that might be helpful:

   1. The Quick Start Guide[1] seems to use "E21524", which is also
      used by some random blog[2] to identify it. 
   2. There's "R1.04" on the silkscreen. 

Perhaps we could incorporate either of those?

 * asus,e21524-ipmi-expansion-card
 * asus,ipmi-expansion-card-r1-04

However, they're not without some risk:

   1. It's hard to tell whether E21524 is properly representative
   2. R1.04 may also problematic as an AST2700-based card will likely
      restart the numbering and risk a collision

Otherwise, I guess there's:

 * asus,ipmi-expansion-card-ast2600
