This is definitely not available in 2.6.  The way I've historically
checked for the existence of lvm driver support in 2.6 has been with:

grep "[0-9] device-mapper$" /proc/misc

This gives you the line containing the minor number of
/dev/mapper/control (which libdevmapper uses for communicating w/ the
kernel).
