nvidia_agp complains about unknown symbols

[Kevin Pakiry]

Hi,

I get the following in kern.log

NVRM: loading NVIDIA Linux x86 NVIDIA Kernel Module  1.0-6111  Tue Jul
27 07:55:38 PDT 2004
nvidia_agp: Unknown symbol agp_bridge
nvidia_agp: Unknown symbol global_cache_flush
nvidia_agp: Unknown symbol agp_memory_reserved
nvidia_agp: Unknown symbol agp_generic_enable
nvidia_agp: Unknown symbol agp_generic_destroy_page
nvidia_agp: Unknown symbol agp_remove_bridge
nvidia_agp: Unknown symbol agp_generic_mask_memory
nvidia_agp: Unknown symbol agp_generic_alloc_by_type
nvidia_agp: Unknown symbol agp_generic_free_by_type
nvidia_agp: Unknown symbol agp_alloc_bridge
nvidia_agp: Unknown symbol agp_add_bridge

nvidia_agp: Unknown symbol agp_generic_free_gatt_table
nvidia_agp: Unknown symbol agp_generic_alloc_page
nvidia_agp: Unknown symbol agp_put_bridge

Could someone please tell me what it means? Is it holding back performance?

I've installed ubuntu on a Dell laptop and am attempting to get X
performance comparable to the installation of Windows XP that it is
dual-booting alongside.

Subjectively the machine is slower than windows XP in moving or
resizing of windows, or even refreshing the display when typing or
browsing. I would hate to think that running GNOME is slower than
windows and am assuming that I've made some configuration error.

I've read what seems to be every forum post with the words 'nvidia' or
'nvagp' in them and have searched the ubuntu-users mailing list
archive back to about November 2004. I've also read the install
instructions on the nvidia site and some google hits that relate to
debian. I've read the BinaryHowTo and the relevant sections of the
Unofficial Starter Guide and have configured the system as follows.
All packages are from initial install repositories on a fresh warty
install.

kernel: linux-686 version 2.6.8.1-14 (boot options noapic nolapic)

nvidia driver: NVRM version: NVIDIA Linux x86 NVIDIA Kernel Module 
1.0-6111  Tue Jul 27 07:55:38 PDT 2004
GCC version:  gcc version 3.3.4 (Debian 1:3.3.4-9ubuntu5)

I've renamed agpgart and intel_agp modules because blacklisting them did nothing

cat /proc/driver/nvidia/agp/status, XF86Config-4, glxinfo, lsmod and
dmesg output are attached.

I've used glxgears as a benchmark. It was run from a terminal with no
other windows open after cold boot.

-approx 700 FPS in a window about 8% of the total screen size
-approx 45 FPS with the window maximized

Is this all i can expect?

machine specs: 
Latitude C810
Intel PIII 1.13 GHz
512 MB RAM
Geforce 2 Go with 32 MB video RAM

Thanks for your time

Kevin
