The doc is a bit outdated - you'd better leave out TT mode, and enable static linking - that should support upto 2,5G+ of RAM.
HIGHMEM still exists, but is slower.

Actually HIGHMEM compiles cleanly, and in fact with 2.6.13 there's no such red warning on HIGHMEM. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
