Here's an updated copy of your second patch that does just that.

I've also included a preview of the ipath patch that depends on this. 
With your original patch, my rework of your second patch, and the new 
ipath patch, the driver is back to working happily for me on top of 
current -git.

I need to test the ipath patch on powerpc before I consider it cooked, 
but I won't have time to do that today.
