It's correct that the default I/O scheduler was one of the things where an Ubuntu "server" kernel would differ from a "desktop" kernel. However, it's prudent in a system with a reasonably high-performance I/O subsystem (whether that box is being used for DRBD or not) to always set the scheduler to deadline either in your /etc/sysfs.conf (as Ubuntu has been shipping with sysfsutils for a while, albeit in universe) or in your bootloader configuration.
