[ale] Time to pick some brains technically

[James P. Kinney III]

Back down to 2.4.18. The release notes on 2.4.19 are sketchy on huge
memory support. There seems to be some issues around allocation above
12G.

Also check the first or second memory module is absolutely perfect. The
map for the himem is held near the end of the first 1G. If that area is
the slightest bit flakey, things go bad fast.

Also, DON'T use the mem=xxx for hugemem hardware. With that compiled in,
and a modern system (it supports 16G, it must be!) it should accept a
memory size probe OK.
