No, fdisk works for me even if /dev/da1s1 isn't created. 
Therefore I'm not seeing the same problem as the OP. For completeness I'm
attaching the output from my machine.

******* Working on device /dev/da1 *******
parameters extracted from in-core disklabel are:

parameters to be used for BIOS calculations are:

Media sector size is 512

This is on a world from Apr. 4 or so. There's this stuff in the logs, but
it seems to be harmless.
