It looks like this bug is showing only when plymouth is used. The latest Ubuntu kernel has booted fine with radeon driver, but with "gfxmode $linux_gfx_mode" deleted from grub config.

However, the system works fine when I disable plymouth (delete "gfxmode $linux_gfx_mode" from grub config). linux-image-3.5.0-21-generic and earlier kernels are working fine. Using Ubuntu 12.10. Upstream 3.8 kernel also has this bug. fglrx driver is unaffected, only the radeon driver is showing problems.
