pci problems (was e1000 not detected in 2.5.53

2.5.53 and 2.5.54 do not seem to find everything on the pci bus on this asus pr-dls m/b

With 2.4.20+ I see

hal3 root # cat /proc/pci

ACPI is enabled in both cases (Won't boot with pci=noacpi)

Any help solving this apprieciated (Just got a gigabit switch for this cluster and keen to get it working with 2.5 as I'm using Uli's nptl)
