I'm not quite sure what you are looking for.  The VERA Linux device
driver runs on the host on the other side of the PCI bus and communicates
with the custom VERA firmware that one must put into the board's
flash memory.  Since it seems that you want to run Linux on the StrongARM,
this device driver won't help.  I didn't write the microengine code,
but we don't really have a device driver running on the StrongARM to
interact with the microengines, per se.  Also, our IXP1200 environment
is little-endian.  There is an unknown amount of work required to test
and make sure it also works when compiled for big-endian operation.
