hi i am attempting to use kernel 2.6.4 with 9.1 i have managed to compile the kernel and modules about 5 times now! but still i am hitting the same problem

when i try to start x i get:
(EE)GARTInit: un able to open /dev/agpgart (no such device)
(EE)I810 (0): AGP GART support is not available make sure your kernel......
(EE) Screen (s) found but none have usable configuration
After the first time this came up i reinstalled and made kernel all over but could not find agpgart in xconfig. been trying all day and this last time i typed modprobe agpgart and recived this message FATAL: Module agpgart already in kernel. hmmm im very confused, please can anyone help me?
