Hacked almost completely really. But that doesn't necessarily spell out any more trouble for it than it does for the x360, and it certainly isn't catching up with the mere number of pirated game copies on the x360, that's been hacked for years. If Sony can achieve with PSN what MS did with detection on Live (especially something as effective as jtag detection), then the rest doesn't even matter all that much for piracy.
Question is whether they will be able to achieve even that because at this point the PS3 can't tell Sony instructions apart from the hackers'.
In terms of actual access to all sorts of stuff it's open way beyond the x360, but aside from the feared game hacks and cheats, that doesn't really bring anything to the piracy scene, it's stuff like emulators, media players, linux obviously, region-free dvd/bd etc.
edit: or rather "won't bring". There doesn't seem to be all much for it yet, well, code sort of needs to be written. Though emulators are there already.
