True, we have tried to throttle back new drivers in favor of 
generalizing existing ones. However, the KSI/Odetics driver is very 
similar to the ex-TrueTime 560, which in turn is very similar to the 
ex-Bancomm bc635/7. The KSI is certainly toast, as is the old Sun SBus, 
so can be deprecated. So far as I know, the 560 was discontinued when 
Symmetricom ate TrueTime, but there are a few 560s still around (I have 
one). Best choice would be a driver that supports both the 560 and 
635/7. If sufficient steam is not available to support the 560, send us 
a 635/7 driver to replace the KSI driver.

There has also been a strong pushback for years now against allowing a new driver into the distribution.  To be honest, I'm not sure what's out there now but I don't see one in the list.  Having said that, if you don't hear otherwise, I'll make you one but I don't know if it will be maintained in the ntp distro.

> The bc635PCI-U (or bc637PCI-U) card have a driver package for Linux that contains a kernel driver which allows the board to be used as a reference time source for the NTP daemon? This turns the computer nto a NTP time server which can also provide accurate time to other NTP clients on the network.
