I blindly added atw to my -current kernel config and it appears to
work.  Yay?  Anyway, good show.  Full dmesg below.  I updated my
sources a few minutes before building (so around 19:50 GMT today).

My usage is very basic; I haven't tried any ifconfig 802.11 parameters
or wiconfig settings.  wlanctl -a works.

I got a little of this, which *may* have knocked my X server down:

    Mar  8 16:20:35 acer /netbsd: atw0: receive ring overrun
    Mar  8 16:20:37 acer last message repeated 493 times
    Mar  8 16:20:37 acer /netbsd: atw0: fatal bus error
    Mar  8 16:20:40 acer /netbsd: atw0: receive ring overrun
    Mar  8 16:21:11 acer last message repeated 15 times
    Mar  8 16:23:13 acer last message repeated 57 times

In case that rings any bells.

Otherwise, atw0 has been working fine, apparently losing packets at a
lower rate than nfe0 had been.  I updated /usr/src, /usr/xsrc, and
/usr/pkgsrc, cross-built -current releases for 3 platforms, ran
firefox and rdesktop, etc., using atw0, without (much) damage.

Very nice.

        Thanks,
        Pete
