I think the referenced i82527-iomem driver

http://svn.berlios.de/wsvn/socketcan/trunk/kernel/2.6/drivers/net/can/old/i82527/?#ac21816bb2f78cb7e7b7b1a75f2ecfed0

is *really* very old ... don't know, if it still works.

AFAIK Wolfgang created the CC770 driver which is the successor of the i82527:

http://svn.berlios.de/wsvn/socketcan/trunk/kernel/2.6/drivers/net/can/cc770/?#a12c70fb51cbd498d785ad6d2ee65ff67

This one is more up to date - but only available in the SVN and not in mainline.
