workaround "black display issue" by disabling kms

$ dmesg
agpgart-ati 0000:00:00.0: Ati IGP320/M chipset
reserve_ram_pages_type failed 0x2c388000-0x2c389000, track 0x10, req0x10

* *

This can be workarounded easly by disabling KMS for this driver :

grep modeset /etc/modprobe.d/radeon.conf 
options radeon modeset=0
