That's not true.
If you use 32 sectors per track you'll create only correctly aligned partitions. (If the disk doesn't use an offset)
Of course you'll need to go to expert mode in fdisk to change the sector count and you can only do that on a yet unpartitioned disk because IIRC it doesn't recalculate the CHS values for already existing partitions.
And you're still screwed with drives that use an offset. :)
