Default Spectacular 8756/Geforce2 Go Explosion

Quoteth Marvin the Martian: An Earth shattering kaboom...

System: Toshiba 5005-S504 running Gentoo ~x86 built with gcc 4.1
512M memory, 16M Geforce2 Go, (I think an) i815 chipset

Uname -a:
Linux lazarus 2.6.16-gentoo-r6 #2 PREEMPT Fri May 5 16:50:56 MST 2006 i686 Intel(R) Celeron(TM) CPU 1000MHz GNU/Linux

When module loads I get the following messages:
NVRM: loading NVIDIA Linux x86 Kernel Module 1.0-8756 Wed Mar 29 14:26:26 PST 2006
NVRM: PAT index 1 already configured for Write-Combining!
NVRM: Aborting, due to PAT already being configured

When I attempt to start Xorg (7.0) with the nvidia module in the xorg.conf the window hangs (though I can still access the machine remotely), X is unkillable, and I get the following spectacular error:

I've tried dozens of combinations of kernel options, module options, and variables in xorg.conf. Even after many searches here, google, and various mailing list archives, I am completely stuck. Heeeeelllllllppppppp!!! *banging head on desk****

Anyone have a clue or hint as to what the problem may be.

I've tried dozes of builds of both vanilla and gentoo kernel sources.

Anyone have a working nvidia module with gcc 4.1?

Isn't gcc 4.1 considered experimental, and may possibly cause breakage?

Perhaps, but everything else on my three systems running 4.1 is fine including the nvidia module on the 2 desktops (6600 & 6800 chips).

Thanks for the response!

Exact same problem here, with Geforce FX 5200, Toshiba Qosmio E15-AV101,
kernel, NVIDIA-8756, gcc 4.0.2, Debian sid.

And I had this problem before, too, with 2.6.13 and 7667. They just broke something and no one had noticed. That time I decided to refrain and used 'nv' driver. Tried this time again, still no luck.

The only solution is to purge these g'oddamn NVIDIA drivers and never look back. The opensource 'nv' driver is no fancy but at least works. This really, really sucks. I feel mad, and my madness was bolstered by the need to register on this g'oddamn forum as well, just to write a simple 'same here, this sucks' line.

joshin, wish you luck. Me, I'll never buy a notebook with an NVIDIA card next time. Something with an integrated intel graphics, which has normal opensource drivers, appeals to me much more now.
