This was added because I requested it a year ago, when I started using
GRUB on PowerPC, powerpc Debian kernels didn't ship a vmlinuz file, only
vmlinux. This is not the case since 2.6.30, as apparently vmlinuz is now
generating a vmlinuz file in postinstall,  and I'm getting two entries for 
the same 2.6.30 kernel, 1 for vmlinux and one for vmlinuz.

More interestingly, if I try to boot the vmlinuz entry I get dropped to
OpenFirmware, with a friendly Illegal Memory Access error message.

In short, I *need* vmlinux to boot my PPC, but need to hide the vmlinuz
entries as they fail and are suppossed to be useful only to boot directly
from OF. Ie, just the contrary that this user is asking for.
