Description Milan Broz 2012-07-23 21:45:11 UTC 
Description of problem:
If there are no topology data (default 512b alignement), fdisk should align new partition start to 1MiB.

Unfortunately, not true if you use SI units:

fdisk /dev/sdb
n -> primary, start is default 2048 sectors (ok), size +256MB
n -> primarym use default

and you will see this:
   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1            2048      502047      250000   83  Linux
/dev/sdb2          502048   312499999   155998976   83  Linux

502048 is not aligned to expected 1MiB. it should be 503808
