Comment 20 for bug 735126

By the way I've tried radeon.blacklist=yes kernel parameter as it was suggested according to some google'd resources. Then radeon did not load indeed, and system booted (checked with lsmod | grep radeon, no result). modprobe'ing radeon did not work then ("illegal parameter" about that radeon.blacklist). When I used insmod with the full path of radeon.ko, screen went black immediately, the same result as my intial bug report.
