Rob,
I would differentiate between CAN and looking for a higher level independent
CAN driver for the OS of your choice and a device and hardware independent
higher layer J1939 part of the software.
This way you should normally be able to use the higher layer J1939 protocol
software on both Windows and Linux without any changes or may be adaptions
to the layer-2 device driver.
If you are looking for pure CAN device drivers, first ask the CAN interface
board manufacturing companies. Each one should provide drivers. And they
do, each one there own API.
For Linux consider using can4linux. The can4linux API is the most often used
and supported by many boards. can4linux is even available for uClinux on
ColdFire boards or for sja1000, i82527 and TwinCAN controllers.
