Several things.  For example, the Fedora kernel has the NPTL patch, and 
I don't believe that Linus's kernel does.  I'm not absolutely certain, 
but I think that the Fedora Core 1 kernel also has a patch, backported 
from Linus's 2.6 kernel, to see 8GB instead of just 4GB; RHEL AS 3.0's 
kernel definitely has this.  FC2, which uses the 2.6 kernel, has the 
SELinux patches put in.  I'm sure that a little Googling will get you 
that information.

None of these are really necessary in the vast majority of cases, since 
I don't know of very many K12LTSP servers that have more than 4GB DRAM.  
NPTL isn't, I've found, that big a deal at all for good performance on 
LTSP; I'm not sure if it even helps at all.
