Yeah, if you try with acceleration you end up with <a class="bz_bug_link bz_status_NEW " title="NEW --- - MacBook Pro 5,x unable to boot [NV96 + NVAC]" href="show_bug.cgi?id=27501">bug 27501</a> (<a class="bz_bug_link bz_status_NEW " title="NEW --- - MacBook Pro 5,x unable to boot [NV96 + NVAC]" href="show_bug.cgi?id=27501">https://bugs.freedesktop.org/show_bug.cgi?id=27501</a>). EFIFB should not be the problem: it is removed by nouveau at some point, to be replaced by nouveaufb, which seems to be not rightly configured (or the accesses to it), bringing screen corruption. I have a 5,3 (iirc) MacBook Pro (mid 2009) 15.6", with the same graphic cards, resolution is also 1440x900.
