You are booting Squeeze using the RHEL5 2.6.18 kernels supplied in /boot
or something like that?

In general there is no requirement to reuse the dom0 kernel as your domU
kernel, although I appreciate that some hosting providers may add that
sort of requirement (or a similar requirement to use one of a blessed
set of kernels).
If you administer dom0 though you can usually use the actual Squeeze
kernel even for a RHEL5 based dom0. For example by using p[yv]grub, or
alien to install the .deb as a .rpm or even just by extracting the
vmlinuz file from the .deb and dropping it in /usr/local/.
