Just don't start drbd at boot. If it's running anyway, heartbeat should
probe and find out that the resources are running.

The process "hangs"? How so? Have you tried stracing the crm_master
process?
I recall that I had some issues with drbd complaining about resources
which mentioned nodes which weren't local; I worked around that by
splitting drbd.conf into several parts and giving each drbd resource its
own separate configfile using the drbdconf attribute.

Shouldn't be, no.

Well, here's hoping that this change of yours truly is the only one
needed to fully support drbd8 ;-)
