Thank you for digging for it. I've also noticed the breakage and reported it,
but haven't got sufficient time for problem analysis.

Fom my ASUS M5A notebook (i915GM-based) reported AGP aperture size was also
0MB before the breakage (and DRM worked properly). Here is the diff between
previous and current DRM:
drm0: <Intel i915GM> on vgapci0
-info: [drm] AGP at 0xfeb80000 0MB
-info: [drm] Initialized i915 1.2.0 20041217
+error: [drm:pid0:drm_load] *ERROR* Card isn't AGP, or couldn't initialize
AGP.
+device_attach: drm0 attach returned 12
