Through the magic of git-bisect I have narrowed it down to this commit
(although I don't know why):

commit 4994be1b3fe9120c88022ff5c0c33f6312b17adb
Author: Yasuaki Ishimatsu <isimatu.yasuaki@jp.fujitsu.com>

    [IA64] Add support for vector domain
    
    Add fundamental support for multiple vector domain. There still exists
    only one vector domain even with this patch. IRQ migration across
    domain is not supported yet by this patch.

As far as why I see this and so far others have not I have 2 guesses.
It could be related to firmware version (I have all my systems with 
the latest available version) or, it could be the version of elilo
(perhaps more of a longshot).

Or, could be my .config file (ok, now that I think of it that may be
more likely).  Attaching my .config here.  This is a custom config
that started out as the fedora 7 .config but I have made some changes
over time.
