I tried this patch with the grub shell,

and it works much better, ie, all of my BSD sub-partitions are
recognized, and their files are listed with TAB completion, even
for a BSD slice on a PC logical partition.

It even `loads' a kernel,

    grub> root (hd0,3,h) 
     Filesystem type is ffs, partition type 0xa5

    grub> kernel /boot/loader^I
     Possible files are: loader loader.help loader.rc loader.4th loader.conf
