The industrial control crowd still uses ISA cards.  You can look for 
companies that serve that market, and expect to pay a premium.

The system chipset will need some support for ISA to work well due to 
differences in interrupt behavior.  There is other hair too I can't 
remember offhand.  I don't know if the designers of any of the amd64 
chipsets built in considerations for ISA.
