It's now available as part of the base RHEL 4.5 installation, which was 
released less than 2 months ago. It's superior to the xensource kernel 
in some ways, since it interacts wiell with the updated grub and allows 
the graceful use of pygrub without having to hand-edit your grub.conf 
files before rebooting, and it drops a "kernelcap" file in 
/etc/ld.so.conf.d/ to avoid the TLS emulation problems. Plus it has the 
documentation with it, which the xensource RPM does not and for which 
building from SRPM fails.
So it's a fairly good kernel. Too bad the network fails between Dom0 and 
DomU with it, which means I'm still sticking with the Xensource 3.1.0 
kernels for my guests.
