There are just a few differences between the 2.4 (1.30h) version of
pcnet32.c and the 2.6 (1.30j) version, as I have tried to keep them
as similar as possible.
The driver was changed in February 2004 to recognize the incorrect
vendor ID so that the ppc workaround was no longer required, and so that
the cards would work in non ppc systems. From the driver perspective
the ppc workaround could be deleted.
On my systems lspci shows all the devices with the correct name whether
it is ppc or x86.
