I assume that what the BIOS detects as hd0 is what Linux identifies as the
/dev/hde (Is this right ?).
What I do not understand with your example is that you tried (hd0,4) that is
/dev/hde5, and (hd0,6) that is /dev/hde7, both without any file system (see
above).
After that you show your fstab, where you mount /dev/hde9 or 11, that is
(hd0,8) and (hd0,10). What don't you try, first, (hd0,8) ?

Other question. The *BSD bootloader put in the MBR modifies the way the
partition of the disk is stored (since the PC standard one is not optimal;
but we are accustomed with...). How this can interfere with the
identification of the partitionning ? Somebody knows ?
