If it help - I've taken Andi's config, compiled the kernel and
didn't find any screwed symbols (nor is System.map nor in /proc/kallsyms).
The kernel - today Linus's git tree:

---
commit 492c2e476eac010962850006c49df326919b284c
Author: Linus Torvalds <torvalds@...ux-foundation.org>
Date:   Sun May 11 17:09:41 2008 -0700

    Linux 2.6.26-rc2
---

The diff btw Andi's config and new one is:

+CONFIG_PCSPKR_PLATFORM=y
-CONFIG_PCNET32_NAPI=y
