[Beowulf] cloning issue, hidden module dependency

Short version: there is an odd problem cloning a Mandriva 2008.1 system
(18.104.22.168 kernel) from one type of motherboard to another. (Source Tyan
S2466 Athlon MP, destination Gigabyte Athlon XP). On previous releases
all that was needed was:
1. image /boot and / (S2466->Gigabyte)
2. put in appropriate /etc/modprobe.conf and /etc/modprobe.preload
3. run lilo
Here that doesn't work. First, I obtained the proper files by doing a
fresh install (with as few packages as possible) on the gigabyte system,
tested that it would reboot ok, then saving /etc before doing the
preceding steps, copying the two modprobe files from the saved /etc.
Once treated as above, the new system (gigabyte) tries to start using a
module from the old system (amd74xx, it should use via82cxxx) and it is
all downhill from there. I tried making a zero length
/etc/sysconfig/harddrake2/previous_hw (which initially contained the
amd74 string), and replacing the entire /etc/udev directory structure
from the saved one, neither of which made any difference. I could not
even find the string amd74 elsewhere in the cloned /etc, other than in
modprobe.conf.s2466 and modprobe.preload.s2466, which were also present
but should not have had any effect.

Or google in groups for: mathog "where is Mandriva 2008.1 hiding"
Contents of modprobe.conf:
alias eth0 8139too
install usb-interface /sbin/modprobe uhci_hcd; /bin/true
install ide-controller /sbin/modprobe via82cxxx; /bin/true
alias pci:v000010ECd00008139sv000010ECsd00008139bc02sc00i00 8139too
Contents of modprobe.preload:
Contents of lilo.conf
Am I missing something obvious?
Any ideas where else the amd74xx module load command might be hidden away?
