Bug#505060: update-grub enters a xen entry for a non-xen kernel

Package: grub
Version: 0.97-47
Severity: normal
As can be seen by looking at menu.lst, update-grub generates Xen
config sections even though Xen kernels are not currently present (I
recently purged them).
Currently installed kernels follow.

Based on the following output, it seems possible that update-grub
assumes that is should create a xen entry if xen is installed, even if
the kernel has no xen support, which is just retarded.
