I disagree. The subject could have been "put our head in the sand and paper over bugs". Please don't do that. There is no reason for any machine not to boot way past "Uncompressing Linux" with the default split. The likely reason it works with the 2G:2G split is because in that case the virtual and physical RAM addresses in the kernel are the same, and therefore missing p2v or v2p conversions are invisible.
