Heh, yeah, it seems to have spurred the original 'hacker' to announce that he's going to work on it (custom firmware) so that people can still use the "other os" option.
Unlikely that I'll go for it (IF it ever works or gets released) - Sony will probably do like MS and start banning people's consoles or screwing something else up if they detect any mods
I'll probably end up wiping out my Linux install. Was looking forward to further tinkering, but since I'd rather just have the console do "everything" else
that it does, the "ultimatum" firmware will likely have to get installed.
