i tried 3.0.0-rc4 today. glitch is still present but i tried changing kernel
config from:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="radeon/R600_rlc.bin radeon/R700_rlc.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"

to:
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE=""

got an error:
[    0.538980] [drm] Loading RV770 Microcode
[   60.896109] [drm:rv770_startup] *ERROR* Failed to load firmware!

but KMS launched with no grid and X started up too!

there is no acceleration however and mesa runs from llvmpipe instead of r600g.
