I suspect that your problem is not related to the partition table. If
you are running a 2.6 kernel, you are probably running udev.
Udev nukes your /dev tree and rebuilds it on boot. It responds to
hotplug events to create the entries in /dev. If such an event isn't
generated when you modify your partition table you won't get the /dev
Try manually using mknod to add the relevant block device.
