I kind of overloaded CAP_SYS_RAWIO to restrict access to bits of arbitrary memory. Maybe this one should require CAP_PTRACE and CAP_DAC_OVERRIDE instead.

What level of interface does it offer? If it's a simple read/ write, then it's no more RAWIO than /dev/hda.
Once upon a time I had a big patch which caught a lot of these things (funny devices, device setup ioctl()s, etc) but nobody seemed interested in it. Really, I think that set of available capabilities needs refactoring.
