sfdisk troubles while tyrin to install ubuntu hoary with FAI

[henning_fai at gmx.de]

Hy,
While the ubuntu warty install from a sarge server with FAI 2.6.5 was easier
than expected, I'm now pretty much stuck while trying to install hoary(the
ubuntu devel stream) with FAI 2.6.6  from a sarge server - everything else
completely the same as with the warty install.

I get some errors from sfdisk like that: 

--- format.log start ---

[...]
Disks found: hdaWarning: extended partition does not start at a cylinder
boundary.
[...]
Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 77520/16/63).
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.)

--- format.log end ---

That's where I run out of ideas for now.

A problem I already solved (for the interested :) ) was this: ubuntu doesn't
have support for 2.4 Kernels and therefore no modutils package for them,
only for 2.6.X Kernels, therefore in the first try now disk had been found
at all, and there where some broken symlinks to insmod.modutils - sorry, I
don't remember the exact location and error ( wil reeproduce if anybody is
interested), but make-fai-nfsroot went well and it took a while until i had
the idea that ubuntu might lacking 2.4 support.
