Apparently "proposed" kernel updates for quantal (3.5.0-37.58) and raring (3.8.0-28.41) both carry the necessary patch: "radeon: Fix system hang issue when using KMS with older cards". Indeed, the updated kernel for raring works fine :-)

When starting without "quiet splash" options, the last kernel messages relate to loading and initializing radeon and drm modules. Same problems are here when trying to boot 12.10 live usb images, both 32- and 64-bit. I'm currently using 3.2 kernel from Precise, which boots fine. According to RH bug report comment, the problem was introduced with an upstream merge commit: f9369910a6225b8d4892c3f20ae740a711cd5ace Ubuntu kernel 3.4.0-5.11 boots fine, 3.5.0-1.1 freezes.
