so basically with all the right patches applied, and GART set to 32MB in the BIOS, Rafael should have more free RAM on his system than ever before :-)
i've put all the patches into x86.git/latest (it's all uploaded already as well), so that should give Rafael a one-stop shop to test it out. [i have not applied the debug patch that changes the aperture test from 32MB to 64MB, and it should be unnecessary as well]
btw., Yinghai, should we perhaps add a WARN_ON() to those places where we waste RAM (such as the "This costs you 64 MB of RAM" message) - so that kerneloops.org can pick those warnings up? Maybe there are other situations where we waste RAM, and people dont realize it.
