Description of problem (for all partners):

On certain OEM systems RHEL-5.3 doesn't install due to nic re-ordering. 

One workaround we used was during kickstart add ksdevice=bootif to make sure we
get the right mac address to connect with.  Unfortunately this caused the
install to use eth1 instead of eth0, which is a difference with regards to
RHEL-5.2.

After bringing in Andy G., he noticed that pci=bfsort wasn't being used like it
was in the 5.2 kernel.  Poking around, he noticed a split path in the acpi
code.  In the legacy pci path, the kernel would lookup the dmi_table entries
for all the blacklisted boxes and perform the correct pci sorting algorithm. 
However, on newer boxes that chose the normal acpi code path, this table was
bypassed.  This was the bug.

Andy has backported an upstream patch that allows both acpi code paths to use
the same blacklist dmi_table correctly.

Can we be more specific about which newer boxes had the problem?

It would make testing go a lot faster.
