The old ps3_storage driver did not support DOS geometry, so there is no
point to start adding code for it.

That's not quite true.  sd applies some heuristics  and has a default
geometry if there is no ->bios_param method.  Then again this whole
gemetry thing really only makes sense on x86.

Would it make sense to have a default implementation in block/ioctl.c?

Maybe.  Someone would have to look all over block drivers if there is
something common enough to be considered default.  Also some drivers
that never ran on x86 never supported it so they'd need a new method
that always returns an error.  I'm not sure whether it'll be worth it
in the end.
