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.
