Unfortunately, you're running the NVidia driver, to which we don't
have the complete source code, so diagnosis is impossible. If you can
temporarily move that module and reboot with "devfs=dall", that might
provide helpful information. Note that you need to enable these DEBUG
options when compiling the kernel:
CONFIG_DEVFS_DEBUG=y
CONFIG_DEBUG_KERNEL=y
CONFIG_DEBUG_HIGHMEM=y
CONFIG_DEBUG_SLAB=y
CONFIG_DEBUG_IOVIRT=y
CONFIG_DEBUG_SPINLOCK=y
CONFIG_DEBUG_BUGVERBOSE=y

You'll want to use -s65536 when running dmesg, to get as much debug
information as possible. And another decoded Oops will be required.
