Thanks for the tip; it was loading the wrong module. If I
load /modules.old/vinum.ko, vinum works.

I didn't install the new world. The HEAD kernel gives me:

Fatal trap 12: page fault while in kernel mode
mp_lock = 00000001; cpuid = 1; = 00000000
fault virtual address	= 0x36
fault code		= supervisor write, page not present
instruction pointer	= 0x8:0xc02eb888
stack pointer		= 0x10:0xce8d47f0
frame pointer		= 0x10:0xce8d48c4
code segment		= base 0x0,  limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 2 (sh)
current thread		= pri 10
 <- SMP: XXX
trap number		= 12

I transcribed the above manually. I don't have any debugging support, so
I'd have to rebuild to provide more information, but it looks like the
same problem Noritoshi Demizu was having.
