When XFree86 begins to load, it dies before any video output comes up on the screen. Looking at the log files, the radeon module seems to load fine, and also seems to detect the video card without any problems. Where it stuffs up is when the int10 driver is loaded and the "Cannot map SYS BIOS" message comes up. I dont think that this problem is specific to the radeon driver as the same error occurs when I switch the video driver to "vesa" in my XF86Config file. Also, I know that video should be working as it works with the Knoppix distribution (abeit with XFree86 4.2.1). Reproducible: Always Steps to Reproduce: 1. emerge xfree and xfree-drm (after setting up a basic system) 2. run xf86config and then edit the XF86config file to get the settings right 3. run "startx" Actual Results: It died Expected Results: Loaded using CFLAGS="-march=pentium3 -O3 -pipe" in my make.conf file using CFLAGS="-O2 -mcpu=i686 -pipe" in make.globals file using USE="acpi cdr dvd -3dnow alsa icc mozilla mysql plotutils perl samba sse usb" in my make.conf file

Created attachment 11182 [details] Kernel config file used to compile the kernel under use when the error occured When compiling the kernel, i unpached the sources of the included ACPI patch and re-patched it with the newest version from source-force. Other than that, the kernel used was a stock gentoo 2.4.20 kernel (ie the result of an "emerge gentoo-sources" command).
I think this is possibly the problem, could you try a kernel with this unset, if possible. CONFIG_GRKERNSEC_KMEM=y (If you're going to use dri, you'll probably need to emerge xfree-drm-4.3.0-r2, or you might hit problems later - but I'd get it working without dri first)
Thanks :-) that appears to have been what the problem was about. Strange though cause the help section on that option made a point of saying that it shouldnt affect XFree86 installations!!
I don't think it should break it either - bios memory is typically read-only, so it's probably not necessary for it to be mapped PROT_WRITE by Xfree. I'll look into that.
