Well, looks like this has been fixed in latest Linus' git. More than fixed, in
fact: not only does the kernel not panic, but modesetting actually works
(appears to fall back to a non-AGP mode of operation).

drm/radeon/kms/agp The wrong AGP chipset can cause a NULL pointer
dereference
Selecting the wrong or no CONFIG_AGP_* chipset can cause a NULL pointer
dereference when combined with CONFIG_DRM_RADEON_KMS and an old system
with a R100 AGP card (should effect other cards too). The agp field
will be set to NULL if no suitable AGP chipset driver is loaded,
drm_agp_acquire already preforms a suitable NULL check so it can be used
directly.
