	I won't comment on which is "better", but the FreeBSD driver is
	based on the NetBSD driver, and an *old* version at that.  This 
	would seem to indicate the FreeBSD driver has bugs that the NetBSD
	folks have since fixed, but I haven't used the FreeBSD 3c509 driver
	myself, and have very little experience with the NetBSD one [so YMMV].

	The NCR driver, I believe, is common to both OS'es.

	As far as bounce buffers for the 3com, I don't think it does DMA, so
	you should find no need for bounce buffers regardless of memory.
