It doesn't seem that the OSKit diskpart library has any handling of
partition type f (Extended LBA).  Looking around in the diskpart
source, it only handles partition type 5 (non-LBA Extended); have a
look at diskpart/find_pcbios.c, for example.  It might be easy to add
support for partition type f, but I dunno.  I only ran into this
problem for the first time this past weekend.

Alternatively, it may be possible with some partitioning tool to
change the type id of the extended partition, but this may make the
logical partitions unusable to some operating systems.
