Re: [Newbie]Why can't I install agpgart on Radeon 32 MB DDR ?

Hmm /dev/agpgart is the device the agpgart module will want to use, however 
if you're using devfs (dev filesystem) this should be created when you load 
the module. If you like me don't use it it should exist I guess tho.....

Not useful but maybe interesting (from 
/usr/src/linux/Documentation/Configure.help (2.4.9 kernel))

CONFIG_AGP
  AGP (Accelerated Graphics Port) is a bus system mainly used to
  connect graphics cards to the rest of the system.
 
  If you have an AGP system and you say Y here, it will be possible to
  use the AGP features of your 3D rendering video card. This code acts
  as a sort of "AGP driver" for the motherboard's chipset. The glx
  module will then be able to program the GART (graphics aperture
  relocation table) registers with appropriate values to transfer
  commands to the card.
 
  If you need more texture memory than you can get with the AGP GART
  (theoretically up to 256 MB, but in practice usually 64 or 128 MB
  due to kernel allocation issues), you could use PCI accesses
  and have up to a couple gigs of texture space.
 
  Note that this is the only means to have XFree4/GLX use
  write-combining with MTRR support on the AGP bus. Without it, OpenGL
  direct rendering will be a lot slower but still faster than PIO.
 
  For the moment, you should probably say N, unless you want to test
  the GLX component for XFree86 3.3.6, which can be downloaded from
  http://utah-glx.sourceforge.net/ , or need to use the 810 Xserver in
  XFree 3.3.6.

  This driver is available as a module. If you want to compile it as a
  module, say M here and read Documentation/modules.txt. The module
  will be called agpgart.o

Ok, I couldn't find it in the docs so I played around with ls and mknod a lil 
it has major number 10 minor 175 and is a character device so I guess you 
should make it like this:

mknod /dev/agpgart c 10 175

I tried this and the ls looks the same so I guess it's ok, I don't know what 
permissions you would want on it so you might wanna experiment with those
I guess rw for everybody if you want to use it as normal user
