You need to create a new hardware template that includes the packages
you want. The easiest way to do this is to take the existing template
(with the 82559 driver), create a copy, rename it, remove the 82559
package and add your CYGPKG_DEVS_ETH_I386_PC_I21143 package.

P.S.: if the driver was not originally written for the PC, you may run
into caching issues (i.e. the driver needs to access uncached memory,
but the PC target doesn't define any uncached address space or have
cache manipulation instructions).
