   kernel has gained a few bytes in the bss section. With the following config
   file, whereas the EPSILON version was using some bytes  of bss, the RELEASE
   kernel's bss is so big that  I get the "bss  overlap, kernel must bzero" at
   boot time.

Harmless.  Actually, I've almost always gotten it.  In any case, if you
re-install the boot blocks that message will actually go away.

   And if one is trying to put too  many things into a  kernel, like the sound
   card driver, MFS, 32 ptys suddenly the kernel is too big to even boot under
   the 640 KB limit (it happened to a friend of mine).

And no wonder, too!  The sound driver is, erm, BIG.  Load it above 1MB if
you must have such a large kernel (look at the LINT config file for an
example of how to do this).

   The filesystem seems a little slower too. I've read  in the RELEASE announ-
   cement that the  buffer  cache  was dynamic   so  it is  funny to  see  the
   following message when I boot (ok, maybe it's dynamic after boot :-))

Hmmmm.  I don't get that feeling at all.

   And last, how does one use the new sound driver ? I've seen  Linux box so I
   know that /dev/audio can  play Sun's .au files  but is there utilities like
   cdsp for it ?

Read /sys/i386/doc/sound.doc.  There's also a package in freebsd.cdrom.com's
packages directory called snd_util_src that you might want to look at.

   Anyway, XFree86 2.0 is   running great on it  and  I'm very happy with  it,
   thanks again for all FreeBSD/NetBSD folks !

Erm.  Thanks, though we are different groups you know! :-)

   using 358 buffers containing 2932736 bytes of memory    <<<<< dynamic ? :-)

Yes.
