Description of problem:

Running 64-bit version on RHEL (4.5 kernel but redhat-release 4u4) with x86
version of firefox installed. System is registered to prod, which right now is
running 416.

up2date-4.4.69-25
firefox.1.5.0.9-0.1.el4

https://rhn.redhat.com/errata/RHSA-2007-0079.html, which is in prod, makes
available firefox.1.5.0.10-0.1.el4. The rhn applet as well as the rhn webui
indicate that this updated package is available. However, running up2date on the
system indicates that firefox is already up2date. Also, scheduling the update to
.10 via the webui seems to work, but once rhn_check is run on the system you get:

'The following packages you requested are already updated:
firefox'

 'rpm -qa --qf "%{name}-%{version}-%{release}.%{arch}\n" | grep fire' on the
system returns firefox-1.5.0.9-0.1.el4.i386

on a system running 64-bit rhel with 64-bit firefox, 

'up2date --arch=i386 firefox' results in 'The following packages you requested
are already updated: and then lists firefox on the next line.'

'If I run just "up2date -u --arch=i386", it lists a ton of rpms and
interestingly, firefox is not one of them.'
