The mkinitrd binary is pretty smart at what to and what to
not include.  E.g., it figures Ext2/3 if the root is Ext2/3
(and Ext2/3 is a filesystem driver), if scsi_hostadapter is
defined in modprobe.conf, then the base scsi, that driver,
plus sd (SCSI disk) drivers, etc...

In the case of 3Ware, you'll have something like:
  alias scsi_hostadapter 3w-xxxx (3w-9xxx for 9000)
In /etc/modprobe.conf (/etc/modules.conf for 2.4/CentOS3)

You can manually force things with "--with" and "--preload"
(to load before the "--with" or other things automagically
included).

In the "old days" I used to manually define the load order of
the SCSI core, 3Ware driver and SCSI disk modules.  But
nowdays, the "alias scsi_hostadapter" ensures all 3 are built
into the initrd.

If it's _not_ required to mount the root (/) filesystem, then
it doesn't go into the initrd.  E.g., filesystem, disk
device, SAN (and any networking required), network (if thin
client/NFS mounted root), etc... are typically loaded as
necessary (NOTE: disk label support is never modular, always
static in vmlinuz itself).

An ISDN card driver shouldn't be put in the initrd.

Ouch.  You shouldn't have to do that.
