9755 hangs computer

[int32]

Hello,

I'm trying to install build 9755 on FreeBSD-6.2 for Quadro FX 550, it hangs right after starting X. I managed to scrap logs from raw /var partition (got to single-user mode, cat /dev/ad4s1f | strings | grep NVIDIA, before running fsck , just in case this helps anyone), so the Xorg.0.log log file is a mess, but I hope it contains useful information: http://karasik.eu.org/misc/nvidia.log .

Also, dmesg http://karasik.eu.org/misc/dmesg and xorg.conf
http://karasik.eu.org/misc/xorg.conf .

I also checked for shared irqs and indeed, judging from the dmesg, GPU and other devices share irq 16. I tried to disable the network and audio cards (didn't help) but I cannot disable the PCI-PCI bridge, and neither can find where to reassign irqs in BIOS.

I don't really know what to try next at this point. Any ideas?

Update: I tried other builds, - 7185, 8762, 9631 - with same results, they all hang the computer. I also tried to disable everything in BIOS and kernel, but even after I disable PCI bus in the BIOS there still are devices (pcib1: <ACPI PCI-PCI bridge> irq 16 at device 1.0 on pci0) that are using irq 16. Compiling kernel without "device pci" led to a panic. Disabling agp didn't help either.

Is there anything else I can do? Please help.

PS. Here's sysctl -a|grep nvidia:
