Which version of kdb have you installed and on which kernel?  kdb v0.x
for 2.2 kernels has limited support for symbols in modules, kdb v1.3
for 2.[34] kernels is much better.  There are no plans to upgrade kdb
v0.x for 2.2 kernels, all our work is on 2.[34] kernels.

In either case you have to load the module before entering kdb.  The
kernel is stopped when kdb is in control.  You cannot do any disk I/O
while kdb is running so you cannot load any modules.
