Lilo warning about /dev/mapper/control



I'm seeing this upon running lilo:

laptop:/home/moseley# lilo
/dev/mapper/control: open failed: No such device
Is device-mapper driver missing from kernel?
/dev/mapper/control: open failed: No such device
Is device-mapper driver missing from kernel?
Incompatible libdevmapper 1.00.17-ioctl (2004-04-19)(compat) and kernel driver 
Added Linux *
Added Linux-2-4-21

Google is finding talk about this problem related to LVM, which I'm not
using.

What's /dev/mapper/control do?  Why would my libdevmapper and the kernel
driver be imcompatible?
