first things first:
stop hijacking my thread! damnit.
secondly: you sure go to panic mode quite easy!
thirdly: I don't know how to recompile kernels (and I probably never will) and you should not ask this here but somewhere else (for example: http://www.broadbandreports.com/
is a good idea, they have an 'All things Unix' forum.)
fourthly: try 'rmmod agpgart' and then 'lsmod', if it is there as a module you should see it. then try 'dmesg | grep agpgart', if it is not there, you don't have it, and then you won't have to recompile your kernel.
fifthly: set the damn 'Option "NvAGP" "0" '! and try that first!
