You should also be looking at making the Apache binary as small as possible:

1) Disable any PHP extensions you don't need.
2) Disable any Apache DSOs you don't need (mod_autoindex, mod_include,
mod_speling[sic], mod_perl, etc.).

The RAM drive is also a good idea, you beat me to it :).

Most server-caliber operating systems already have file-based caching, so the
require()/include() stuff is dealt with. It uses a lot more than 10MB
sometimes, though.
