I've helped him on this thread:
(he fixed the r/w mount problem himself, I thought it was because of the wrong 22Gb disk size)
I have tried FreeBSD now but got a kernel error right after I start the disk with petitboot. is this a known problem? Maybe because it looks at the installed Red Ribbon distro kernel on the HD?
I only have a IRC program without ssl, otherwise I would jump to your IRC for this problem.
Sorry to hear about your PS3
