AFAIK the FlexCAN driver is not part of the 2.6.35, so you probably have a
board support package that added this driver manually. Because i wonder how
the CAN drivers output emerges before the 'CAN device driver interface' which
needs to be loaded before. Can you send a 'real' dmesg output?
Can you also send the output of
ip -details link show can0
???
Maybe we should wait for the FlexCAN guys ...or you could ask the provider of
your board support package.
