Without digging too deep into the special properties of your CAN 
hardware and your source code modifications: It seems to me that your 
CAN controller has two distinct IO regions whereas rtcan_isa assumes 
that there is one IO region of 32 bytes which belongs to the SJA1000. 
What are the two regions of your hardware for especially, the one with 
only 8 bytes? You should check whether you access those SJA1000 
registers correctly. A look into rtcan_sja1000_regs.h may help you.

However, as Wolfgang already suggested, there is at least one driver 
available for plain Linux which should work with your CAN controller. If 
you tested this driver successfully you could take a look into its 
source to get further hints for your Xenomai driver.
