how to create device nodes when devfs doesn't do it?

After googling and searching in the mailing list archive I still can't 
figure out how to make device nodes in -current when devfs doesn't do this 
automatically. I have an external USB-drive (external 3.5" case with leftover 
1.6 GB HD) from which I want to mount /dev/da0s4h. It works fine in -stable, 
after MAKEDEV'ing the node, but on -current I only get da0s4. My USB flash 
drive (Apacer Handysteno) works fine; /dev/da0s1d is created after insertion 
of the flash drive (I reformatted it to UFS, but it also worked with msdosfs, 
though slower).

Using disklabel on the external USB drive shows some warnings:

phys9911# disklabel da0s4
# /dev/da0s4:
8 partitions:
#        size   offset    fstype   [fsize bsize bps/cpg]
a:    72513       63    4.2BSD     1024  8192    16
b:   269892    72576      swap
c:  3324825       63    unused        0     0         # "raw" part, don't edit

e:    49896   474012    4.2BSD     1024  8192    16
g:   716688   523908    4.2BSD     1024  8192    16
h:  2084292  1240596    4.2BSD     1024  8192    16
disklabel: partition c doesn't start at 0!
disklabel: partition c doesn't cover the whole unit!
disklabel: An incorrect partition c may cause problems for standard system utilities
FWIW, this drive contains an OpenBSD 2.7 installation. All partitioning
was done by the OpenBSD installer.

Any suggestion? (Apart from newfs...)
