Hi Dave,
I can't remove the AGP chipset module on my boxes. Looks like the AGP chipset driver holds a reference on itself and thus makes removal impossible.
From what I understand, as soon as intel_agp is loaded, agp_intel_probe is called. It gets a reference on intel_agp module through !try_module_get(bridge->driver->owner) in agp_add_bridge. Then this reference can only be released through module_put in agp_remove_bridge which is called agp_intel_remove which is only called when removing the module.
Thus it looks impossible to remove this module at all. And I think the problem occurs with all other AGP chipset drivers.
I hope the reason is not just that module removal support is not important in 2.6 :) It looks strange to implement a module removal routine if we know it can't be used :)
