Why /dev/serno doesn't show USB disk? also SMP version

[Pierre Abbat]

I pulled the laptop disk out of the USB adapter and put it in the laptop 
(which didn't work, apparently the laptop doesn't recognize a disk bigger 
than 128 GB). I then put it back in the adapter and plugged it in. It came up 
as da9. I tried to mount it and got an error, because fstab says it's da8 (I 
had forgotten to turn off cryptsetup). /dev/serno doesn't show any entry for 
it. How come?

The kernel version I'm running is:
DragonFly darner.ixazon.lan 2.11-DEVELOPMENT DragonFly 
v2.11.0.203.g0e5ac-DEVELOPMENT #2: Mon May 16 09:57:06 UTC 2011     
root at darner.ixazon.lan:/usr/obj/usr/src/sys/GENERIC_SMP  i386
This is one day after Sephe announced "SMP kernel now boots UP system", but 
that's the compilation date. If I boot the kernel I'm running on a UP system, 
what'll happen? Should I recompile?
