Default "Failed to allocate DMA push buffer" on amd64 with 1.0-8762

so far I failed to get a GeForce 7900 GTX (actually two of them for SLI...) running with XFree 4.3 on a Debian system. I already installed the latest driver 1.0-8762 and the kernel module is loaded.

However, starting the XServer aborts with:
(EE) NVIDIA(0): Unable to allocate DMA memory
(EE) NVIDIA(0): Push buffer DMA allocation failed
(EE) NVIDIA(0): *** Aborting ***
(EE) NVIDIA(0): Failed to allocate DMA push buffer
(EE) NVIDIA(0): *** Aborting ***
Also dmesg shows some errors:
NVRM: nv_kern_mmap: invalid offset: 0x00010000 @ 0x000000005a770000 (PCI)
NVRM: nv_kern_mmap: invalid offset: 0x00010000 @ 0x000000005acbf000 (PCI)
I attached the log from

Any hints how to proceed?

Thanks in advance.
