This remark triggered me. Booting without USB and PCIe will be a
challenge I'll tackle another day, but looking at the differences in
hardware as observed by the kernel is easy.

Attached are two files containing the lshw output for both the kirkwood
and marvell kernel flavors. Except for the obvious differences like
versions, I find the below differences. I do not know if these
differences are related to the observed issues.

- IRQ is in the 3x range on marvell and 8x range in kirkwood.
- On marvell PCI bridges have additional capabilities: pciexpress and
cap_list
- usbhost:0 and usbhost:1 swapped between marvell and kirkwood.

For reverence I also added the 6281 lshw output. lshw versions between
devices are different.
