Yes. The driver for the Token Ring card must understand RIFs. For example, 
it sends an explorer frame and processes the replies to choose the best 
path to a destination. (Most drivers just use the first reply and reset the 
direction bit.) The replies will have the bridge and ring numbers that were 
filled in by the bridges.

Contrast this to bridging used on Ethernet. Ethernet end nodes don't have 
to know if they are in a bridged environment. That's why it's called 
transparent bridging. It's much more elegant! Source-route bridging is 
considered an abomination by most experts. &;-)
