fdisk -l doesn't see it, but it does seem to edit it:

[root at xen1 ~]# fdisk -l
[root at xen1 ~]# fdisk /dev/xvda

The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)
