How interesting.  I was under the impression that dev->sysdata was always
a copy of the bus's.  If that's not guaranteed, then we're just going
to have to dereference the additional pointer and use the bus' sysdata.

"Next the statesmen will invent cheap lies, putting the blame upon 
the nation that is attacked, and every man will be glad of those
conscience-soothing falsities, and will diligently study them, and refuse
to examine any refutations of them; and thus he will by and by convince 
himself that the war is just, and will thank God for the better sleep 
he enjoys after this process of grotesque self-deception." -- Mark Twain
