Doing SIGBUS on ia64 was painful, due to the way the CPU chooses to not generate errors until bad data is actually consumed, but that's the approach we're taking at the moment. I'd rather have the ioctls though, so I'm glad you're up for it. My hope is that we can have a unified Linux device access method in X and get rid of all (or at least most) of the ppc/sparc/ia64/etc. specific hacks in the tree...
