This keeps coming up on linux-scsi; basically these are ioctls that
are called by some binary-only (and x86-binary-only at that) management
program.  so if they want to ship an ia64 version of their management
program, they'll have to fix this; otherwise the addresses are guaranteed
to be in the lower 32 bits of the address space.

"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
