Almost.  initrd is an initial ramdisk - you only ever have the one
kernel, but this initial ramdisk can contain scripts and modules so that
a distro can use modules for everything, even for the disk-driver and
filesystem of the real root device.

 Anyway, your problem with /dev/hdb3 leads me to offer a couple of

did you compile in the ext3 filesystem (I think you said it was ext3),
and courtesy of udev, did you remember to compile in support for
hot-pluggable devices (CONFIG_HOTPLUG) ?

 das eine Mal als Tragödie, das andere Mal als Farce
