The "proper" way to fix this is to do it on the F14 system.

Change your password entry to have uid:gid of 1000:1000.  Make the change to the
group file to change it to 1000 as well.

Then, go to all the top of all partitions/directories owned by 500 and chown -R
1000:1000.  In other words, make all the changes on the F14 side. 

I had to go through this process when I installed F16 since my RHELv4 system 
had me
as 500:500 and I NFS mount my directories from there.  Just took 5 or so 
minutes. 

Reinstalls are never needed to change a user's gid/uid.
