nvidia-agp won't load, unresolved symbols

[Sebastian Kügler]

I'm trying to use Xorg with nvidia-agp, rather than agpgart. I'm using this 
setup in my breezy install, it's stable about 20% faster (admittedly, 
measured FPS in glxgears. Yeah, I know...).

In Dapper (2.6.15, tested with -686 and -k7 kernels), nvidia-agp is not 
loadable without having agpgart loaded first. That results in that I can only 
use nvidia.ko with agpgart, while it should be possible to use the nvidia AGP 
driver.

So basically, I should be able to load nvidia-agp and nvidia *without* 
agpgart. If I move agpgart.ko out of the way, however, nvidia-agp is not 
loadable due to unresolved symbols:

[4294803.666000] nvidia_agp: Unknown symbol agp_bridge
[4294803.666000] nvidia_agp: Unknown symbol global_cache_flush
[4294803.666000] nvidia_agp: Unknown symbol agp_memory_reserved
[4294803.666000] nvidia_agp: Unknown symbol agp_generic_enable

[4294803.666000] nvidia_agp: Unknown symbol agp_off
[4294803.666000] nvidia_agp: Unknown symbol agp_remove_bridge

[4294803.666000] nvidia_agp: Unknown symbol agp_alloc_bridge
[4294803.666000] nvidia_agp: Unknown symbol agp_add_bridge
[4294803.666000] nvidia_agp: Unknown symbol agp_generic_create_gatt_table
[4294803.666000] nvidia_agp: Unknown symbol agp_generic_free_gatt_table
[4294803.666000] nvidia_agp: Unknown symbol agp_generic_alloc_page
[4294803.666000] nvidia_agp: Unknown symbol agp_put_bridge

Setting
Option      "NVAgp" "1" 
in xorg.conf has no effect, it falls back to agpgart.

When running Xorg, I can rmmod nvidia-agp without problems, so it does not use 
that driver apparently.

In short: 
* nvidia.ko + agpgart.ko: works
* nvidia.ko + nvidia-agp.ko + agpgart: works, nvidia-agp is unused
* nvidia.ko + nvidia-agp: nogo, nvidia-agp wants agpgart

Bug / feature?
