2.6.30 is missing a patch that makes load-detect work.

(It's in Eric's tree, commit 03d6069912babc07a3da20e715dd6a5dc8f0f867):

    drm/i915: Hook connector to encoder during load detection (fixes tv/vga detect)
    
    With the DRM-driven DPMS code, encoders are considered idle unless a
    connector is hooked to them, so mode setting is skipped. This makes load
    detection fail as none of the hardware is enabled.
