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.
