NDIS1.1 can not support bcm4318 in 64bit mode, but 32bit mode. This 
issue has nothing to do with APIC.

Thereafter I made a 32bit boot and installed the 32bit drivers from this 
mode. This worked fine, so i continued with the project and at the end i 
ended up with the solution of only to copy the 64bit drivers to their 
locations without making use of add_drv for the 64bit drivers.  this did 
the trick and everything seems to work fine.
