sfdisk errors

Hi,

I encountered some strange errors regarding sfdisk. The host has been
installed with FAI 2.5.4 (kernel 2.4) and now I want to reinstall it FAI
2.8.3 (kernel 2.6.11.12). The partition layout is the same since the last
installation. hda2 should be preserved.

It looks like, that sfdisk now wants to use a different harddisk geometry
from the first partitioning. As a result, sfdisk isn't able to takeover
the layout and wants to do a new paritioning. However, I don't want it to
do so :)

Has somebody an idea, what could be done to solve this?

Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 155061/16/63).
For this listing I'll assume that geometry.

sfdisk: I don't like these partitions - nothing changed.
(If you really want this, use the --force option.)
