I too had these problems.  But on my Broadcom device using NDISulator. 
When I moved my laptop over to FreeBSD I found no drivers for my miniPCI 
broadcom card... so I ran NDISulator.

It worked well for the most part... but I did notice the 'No buffer 
space available' errors.  I was making an exodus from Windows anyways 
and I decided I'd rather not drag along some drivers, so I moved to an 
Atheros miniPCI card.  It is supported by native drivers.  I have had no 
trouble with them.  Have you tried the FreeBSD drivers for the atheros 
device?

If your determined to use NDISulator... theres a fair amount of info out 
there.  googling for "Project Evil" and/or NDISulator will provide some 
insight.  I have seen posts regarding this particular error... with 
suggested solutions... but I bailed on the broadcom device.
