Nope, the kernels are not that similar. Porting might be
a short way in many cases, but we don't live in a world
where all drivers/specs are open.

FreeBSD usually target popular hardware. So, basically,
yes - the more Macs, the better support.

While the kernels are not all that similar there already is
Darwin on  
Intel, lots of former key FreeBSD talent now works for
Apple, and  
then without any fanfare MacOS X is found to support several
hardware  
items which have been near and dear to FreeBSD in the past
such as  
the Intel Etherexpress Pro NIC. Simply pulled a PCI NIC from
my  
FreeBSD PC and dropped it right into my G4 PowerMac. Same
holds true  
for several other commodity NICs.

Mostly the same for a $10 5-port NEC chipset USB2 card. I
can wake  
from sleep thru the Intel Etherexpress NIC but can not wake
from  
sleep with the NEC USB2. That's not necessarily a bad
thing, in fact  
now that I know it, its a feature. Plugged printers into the
NEC and  
now if the Mac is sleeping and I see the printer is still on
I can  
turn the printer off without waking the Mac. Previously any
activity  
on the USB bus would wake the Mac.
