Yes. I'm sure Ross meant just the centosplus kernel, not the

I have been helping with the maintenance of centosplus kernels for
about a year. And yes, I am involved in the ELRepo project as well (I
must admit that most of crucial works are the results of other
[OT] Just to defend myself ... I supply the src.rpm for the cplus
kernel usually within 24 hours for each kernel update. "is always
behind" may be a bit misleading ... :-) [/OT]
As Tim mentioned, enabling certain options for additional device
support is not the only thing cplus kernels offer. There are patches
that are applied which cannot be done in the distro kernels. For
example, there are currently 4 patches in the cplus kernel. Two of
them will be in the upcoming CentOS 5.4.
I think that many, if not all, of the kernel drivers enabled in the
cplus kernel can / will be replaced by kABI-tracking kmods. In fact,
Alan Bartlett made a list of such modules some time ago. At this
moment, kmods for ntfs, ufs, jfs, reiserfs, and video4linux are
available from ELRepo.

Indeed, my _waist_ is just fine. :-P
