It looks like the fix was actually isolated upstream: http://comments.gmane.org/gmane.linux.kernel/1247563 But debate on how to best implement it without effecting other platforms has stalled it's progress. More investigation is required to determine it's current status. Please keep comments here

That's never how it works. multipath has no kernel module loading ability. Would make a nice feature though. I admit that discovering which dh is the necessary one is a bit arcane and not well documented anywhere. The best practice here is to load the necessary device handler into your initrd so
