As has been discussed here before, hda minors shift,
when BSD disklabel or Solaris partition support is switched on
under Linux using msdos partitions (mostly i386).
If you thus correct your /etc/fstab, and later boot a 2.0.33
kernel, the old mapping is in place again, yielding the
former assignments. What is even more unfortunate is that
(c)fdisk disagrees with 2.1.x kernels wrt the devices, since
(c)fdisk does not know of them (and probably should not).
So I did this patch to append the slices of alien partitions
at the end, leaving the previous mapping intact.
I have tested this patch very lightly (mounting of FreeBSD
partitions/slices works).
Happy hacking, Heiko
