Are you sure the kernel sources are matched with your kernel. I find this
rather odd.
The Cuse4BSD printout is called from a SYSINIT. If sysinits don't work then
something fundamental is wrong. Also check:
find /boot -name "cuse4bsd*"
printf("Cuse4BSD v%d.%d.%d @ /dev/cuse\n",
(CUSE_VERSION >> 16) & 0xFF, (CUSE_VERSION >> 8) & 0xFF,
(CUSE_VERSION >> 0) & 0xFF);
}
SYSINIT(cuse_kern_init, SI_SUB_DEVFS, SI_ORDER_ANY, cuse_kern_init, 0);
