These can be found in (semi-)supported branches still:

- loop.ko:
  + 3.0.101-std-def-alt0.M60P.1
  + 3.4.96-led-ws-alt0.M70P.1
- aufs.ko:
  + 2.6.32-el-smp-alt31
  + 3.4.96-led-ws-alt0.M70P.1

ehci_marvell.ko isn't found in contemporary sisyphus/armh
kernels but let's purge it later during archdep rewrite.

NB: libusual.ko has been renamed to usb-libusual.ko as of p6
    (not to be found in p7 anymore), and nls_base.ko was in
    2.6.32 kernels as of p6 but not there in p7; purge these
    somewhere down the road.
