At the lilo prompt, or if you get a lilo menu just hit <Esc> to get the lilo prompt, type linux single. That should boot you into a single user shell. From there you can disable alsa using the /sbin/chkconfig command.
If you can't get to a prompt using linux single then try booting Mandrake CD#1 and at prompt hit <F1> then type rescue. After booting into rescue tell it to mount your partitions under /mnt then go to console and type chroot /mnt and the chkconfig commands.
