Agreed.  After a bit more testing, I found that there were preprocessor 
warnings generated due to symbols being defined multiple times between 
your i2c.h and the omap1510.h (notably inb(), outb() and the like).  I 
came up with pretty much the same solution as you, and am running a 
MAKEALL test now just to be sure there are no issues this time. 
Assuming not, I'll re-send just the above changes as a patch to resolve 
this.

Thanks.
