Yep, the only x86 kernel on the XFS-PR0.9 CD with HIGHMEM configured is
the i686-enterprise kernel:

kernel-2.4.0-i686-enterprise.config:CONFIG_HIGHMEM64G=y
kernel-2.4.0-i686-enterprise.config:CONFIG_HIGHMEM=y

There are other differences in the enterprise kernel as well, of course
- although I'm not sure what all, offhand...  the XFS kernel RPMs follow
Red Hat's configs very closely.
