AFAIK if you partition a harddisk which is not in use (not mounted any 
of its partitions), the kernel is able to re-read the partition table 
(and says so in the syslog). that way i've created partitions on 
harddisks without rebooting.

i think [s|c]fdisk complains, if it can't re-read the table:

The partition table has been altered!
Calling ioctl() to re-read partition table.
WARNING: Re-reading the partition table failed with error 16: Device or 
resource busy.
The kernel still uses the old table.
The new table will be used at the next reboot.
Syncing disks.
