I have a Sony Vaio SE laptop with a Radeon HD 6630M (Turks) and Intel HD 3000 integrated graphics, and am running Gentoo Linux amd64 with kernel 3.2.1-r2 and
xf86-video-ati 6.14.3.  I have the microcode installed and the Turks firmware built into the kernel, and KMS is enabled in grub.conf.

At boot, the kernel output on VT1 freezes after about two seconds.  However, I am still able to switch to other terminals, log in, and enter commands, but
cannot see what I am doing due to the boot text being frozen on the screen.

dmesg shows radeon being loaded normally, but Xorg.0.log shows a "no devices detected" error.  This occurs both with no xorg.conf and with an xorg.conf that
forces radeon to be loaded.  The Intel graphics were disabled in the kernel to be sure they weren't conflicting.  Furthermore, dmesg displays the following

"[Firmware Bug]: Duplicate ACPI video bus devices for the same VGA controller, please try module parameter "video.allow_duplicates=1"if the current driver
doesn't work."

Adding the suggested parameter does not remove the error.
