Why not?
It shows all minors it can handle.
Currently you have one configured, and one unconfigured drbd device.
If you had loaded the module with minor_count=27, it would show you 
26 unconfigured devices.

if you want LVM on top of drbd, you need to use LVM2 because of inherent
limitations of lvm v1.

search for LVM2 on top of drbd in google,
or on http://search.gmane.org , group drbd.

there should be a link in the faq, too, but I am not too sure about this.
