(I'm using the latest udev, 032.) After I switched to the new hotplug 23092004 (and tried also coldplug, but it doesn't work either), /dev/agpgart isn't created anymore (I put agpgart in /etc/modules.autoload.d/kernel26). (I tried also compiling it INTO the kernel.) lsmod shows agpgart isn't used by anyone, so i tried loading i915 for my card (from the new x11-drm pkg), though the latter should be loaded by X when he find agpgart anyway. so i discovered that i915 built from x11-drm segfaults (before upgrading to 2.6.8-gentoo-r5 & hotplug+coldplug it didn't, so I don't know what one provoked the problem here, gonna check): -------------- [drm:drm_probe] *ERROR* Cannot initialize the agpgart module.

What to do then? I reasoned that since modprobe agpgart figured right in dmesg and no error was showed, it's just udev/somewhat-else that doesn't create /dev/agpgart though the module is loaded. So, I went to /dev/, and typed mknod agpgart c 10 175 chmod ugo+rwx agpgart just to be sure it's not a perm problem (only for testing!). startx reports that no /dev/agpgart is found... dunno if it helps, but also mplayer doesn't work as it should with the x11 vo: vo: X11 running at 1024x768 with depth 24 and 32 bpp (":0.0" => local display) Disabling DPMS It seems there is no Xvideo support for your video card available.

You should not load agpgart on 2.6 kernels. Instead you load intel-agp pr ati-agp or something and agpgart gets loaded as dependency.
whoops, nobody told me that, thanks.
