I tested the package on my iMac DV. Thanks!

Works fine.

The test on my Alu G4 book is outstanding. I wanted to include the 
adb.diff from Nathan as well. But unfortunately I seem to miss a file, 
viareg.h for/from his patch. If I get this file soon I can continue 
building, otherwise I'll build w/o adb support. (Somehow important since 
I do not like to attach a USB kbd to my G4 Alu Book.)

Let you know about the outcome.

Thanks again,
