Yes.  Your modprobe.conf-derived behavior in the initrd is only refreshed
if you re-mkinitrd it.

If you ever want/need to check what's in the initrd you can do something
along the lines of:

$ gzip -cd /boot/initrd-2.6.18-274.3.1.el5.img | strings | grep dasd=
insmod /lib/dasd_mod.ko dasd=101-104(diag),200-210

...which is a quick way of seeing where your problem lies when you're
sitting at a recovery prompt 8)
