I added my own entry in the rc.sysinit file after the root filesystem is
made writable. So, here is my own entry (two lines below # DS ...:

# The root filesystem is now read-write, so we can now log via syslog()
directly..
if [ -n "$IN_INITLOG" ]; then
    IN_INITLOG=
fi

# DS Ok, now scan all volume groups for LVM and activate them
/sbin/vgscan
/sbin/vgchange -a y

if ! grep -iq nomodules /proc/cmdline >/dev/null 2>&1 && [ -f
/proc/ksyms ]; then
    USEMODULES=y
else
    USEMODULES=
fi

It is near line 315 in my rc.sysinit file.

I also have the initrd image made with lvmcreate_initrd and the
appropriate entry in the lilo.conf file. I am using kernel 2.4.17 as
well.
