1MiB boundaries are optimal for they also align with 128KiB and 256KiB
which could be used in solid disk hardware.

Now how to do this using fdisk:
My thought of using of 32 heads and 64 sectors per cylinder doesn't work for older fdisk versions (openSUSE11.2). 
Let's try the other way round:
"fdisk -L -H 64 -S 32 /dev/sdb" 
I did create an new empty DOS partition table with "o". And I started the first partition at cylinder 2 
This looks like:
----------------------
root@maci:/etc# fdisk -L -l  /dev/sdb
GNU Fdisk 1.2.4
....
Disk /dev/sdb: 4 GB, 4127195136 bytes
64 heads, 32 sectors/track, 3936 cylinders
Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System 
/dev/sdb1               2         935      957408    c  FAT32 LBA
/dev/sdb2   *         936        3936     3072000   83  Linux
----------------------
Now showing with sector numbers:
----------------------
root@maci:/etc# fdisk -L -l -u /dev/sdb
GNU Fdisk 1.2.4
....
Disk /dev/sdb: 4 GB, 4127195136 bytes
64 heads, 32 sectors/track, 3936 cylinders, total 8060928 sectors
Units = sectors of 1 * 512 = 512 bytes

   Device Boot      Start         End      Blocks   Id  System 
/dev/sdb1            2048     1914879      957408    c  FAT32 LBA
/dev/sdb2   *     1914880     8060927     3072000   83  Linux
----------------------
I think such a restriction when partitioning should be totally compatible with Vista/Win7 and should be performant using any of the solid state disks. ... But I don't know how to consider an offset of -1 of some of those disks :(

Binary package hint: partman-auto

I would like to give people a try using ubuntu 
but I fear to setup some trouble for them if they use win7.
This isssue is described here:

It is a MS related partitioning bug.

To get around there are 3 ways possible:

C) Most easily: You typically purchased a notebook where there are 3 primary partitions. Ubuntu Release Notes should mention that in case of dual boot  you should only create one primary root partition not any more ! (no swap, no home, no further extended)

B) A more sophisticated approach: Since Vista Windows needs a megabyte free space just in front of every first primary partition and a megabyte free space in front of every first logical partition in every extended partition. Partition your disk accordingly or give Windows7 Partitioniong Tool a try to configure your harddisk appropriet for a linux install (more easy?)

C) Feature request: make linux partitioning tools feature a windows7 compatible mode.
