yeah, i guess so. Right now i only ran into the build failure so there's hope :) Here's a config that fails to build for sure:

note, on 32-bit there's a yet unfixed initrd corruption bug i've bisected back to:

| 510be56adc4bb9fb229637a8e89268d987263614 is first bad commit | commit 510be56adc4bb9fb229637a8e89268d987263614 | Author: Yinghai Lu <yhlu...@gmail.com> | Date: Tue Jun 24 04:10:47 2008 -0700 | | x86: introduce init_memory_mapping for 32bit

so if you see something like that it's probably not a bug introduced by your changes. (and maybe you'll see why the above commit is buggy, i havent figured it out yet)
