[SLE] Please help about Nvidia

Hi all, I'm running SuSE 9.1, my graphic card is a Nvidia GEForce FX5900. I'm able to compile and load the Nvidia module with the 2.6.4 kernel. But I tried Mantel's kernels, with this kernel the module compiles but doesn't load !! It was the same with Linux 9.0, I reported to Manteh who replies that it worked with their Nvidia tester, and that's all. I tried with the kernel.org kernel-2.6.7rc2 and it works. Has someone the Nvidia module workink with the latest Mantel's kernels ? If so please help me, if not please report so that I can continue to discuss with Mantel. Thanks in advance for reply. Michel.
