I don't know, Mick. I have FB_MODE_HELPERS=y? or maybe because I have CONFIG_DRM_KMS_HELPER=m CONFIG_DRM_TTM=m these won't kick in until the module loads. Also, I use genkernel to build all the init stuff for me. I also have MTRR sanitizer turned on. Here are the other kernel settings I have, again, on the Athlon II X4 system, that could be relevant: CONFIG_VIDEO_OUTPUT_CONTROL=m CONFIG_FB=y CONFIG_FIRMWARE_EDID=y CONFIG_FB_DDC=y CONFIG_FB_BOOT_VESA_SUPPORT=y CONFIG_FB_CFB_FILLRECT=y CONFIG_FB_CFB_COPYAREA=y CONFIG_FB_CFB_IMAGEBLIT=y Now last night on my Phenom 940, I was unable to get KDE to remain stable unless I turned on KMS. Now that system, too, is stable as far as the half hour of testing I performed was able to show.
