Firstly there is no situation in which reiserfs.ko will be loaded from a 
reiserfs partition.

If the root file system is reiserfs then reiserfs.ko will (or at least should) 
be included in the initrd.  The GRUB support for ReiserFS is based on the 
file /boot/grub/reiserfs_stage1_5 which is only needed for /boot on ReiserFS.

Some people believe that /boot should be a separate file system to the root 
file system regardless of all other issues.  All systems which use LVM for 
the root file system on Fedora (the default partitioning involves LVM) will 
have a separate /boot file system because GRUB apparently doesn't support LVM 
(yet).

So having a /boot with Ext2/3 is an easy solution to any ReiserFS booting 
issues, and a solution that will be forced on the users if they use LVM.  
When using a small /boot file system ReiserFS is not a good choice.  A quick 
test showed that Ext3 gave 18M more usable disk space from a 100M file system 
than ReiserFS, this will essentially force all LVM users to use Ext3 
for /boot.

This can be done automatically through the Anaconda GUI or through kickstart.  
Just specify that /boot is to be a separate partition of type Ext3.
