We are also looking at using the V25 in a design.  In our design we
intend to interface an expansion card containing the V25+ (10 MHz
enhanced V25) to an AT over the AT I/O channel.  Has anyone on the
net done anything similar?

According to the NEC documentation on the V25 Plus (or uPD70325),
the enhancements of the V25+ over the V25 include
 - DMA transfer rates to 5Mbytes/sec
 - additional serial channel status flags
 - improved memory access timing 
 - enhanced software control of register bank context switching

Also, according to our NEC reps, they will be coming out with a version
in the fourth quarter which will have the real-time  Vertex (sp?) OS 
on the chip.  This is in addition to the current part which contains RTOS.
