I remember having messed with this a while ago...
The d_type field doesn't have a definition for IDE yet.
(ESDI might be close, but not the same.)

The d_type numbers in <sys/disklabel.h> of different vendors
are diverging. 1-6 and 10 seem to be agreed on on the
platforms I checked (Net/FreeBSD, DEC). 7/8/11 are equal
between the BSDs. DEC has assigned the 9 to "DTYPE_IDE",
it is free in both Net/FreeBSD. If there is no authority,
perhaps we should add a similar definition.

The i386 bootloader does a similar check (in some pre-1.3 kernel
compatibility code - see i386/stand/lib/exec.c). Here only SCSI
is checked for - everything else is treated as "wd".

Only the lp->d_type part, please. The lp->d_typename is set below
to the model name read from the disk.
