Are you seeing the message "X accessible regions found. Only the first
one will be used"?

Yes, you'll have to create a gendisk for every set bit in
ps3_storage_device.accessible_regions.

Currently it always uses ps3_storage_device.region_idx as the region to use.
Probably you want to modify ps3stor_read_write_sectors() to take the region
number as a parameter.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
