RH has never supported reiserfs (and it's no longer the default offered 
by SUSE).

Preferably, use one of the make config choices; I've taken to .config 
with vim on occasion, and there's sometimes consequences.

You will also need (absolutely need) the reiserfs toolset. It seems to 
me from reports I've seen that reiserfs is a little fragile, and you 
really need the ability to fsck it.

Probably, CentOS has all of what you need in one of its repos, and they 
are compatible with RHEL and so SL.
