I have an 'Intel Extreme Graphics' chip (82845, supported like i810) in a machine with 2 GB of memory. When I boot knoppix, I get a message to the effect that the 'insmod' for i810 fauls becuase 'agpgart' has a memory allocation error; and the X-server runs in 640x480 mode.

My monitor is capable of everything up to 1600x1200.

What do I specify to get my video hardware working to its capability ?
