Re: IBM ThinkPad T21 -- any hope for sound support?

Adam,

I did a pretty extensive write up on the T23 I recently purchased.  I imagine 
the T21 won't be too far off.  Really need to get that write up on a web page 
someplace as an easier reference that I can actually update.

Anyhow, rather than repost all of that, here are the relevant articles I wrote 
in the archives.

Thinkpad T23 Setup (part 1)

Thinkpad T23 Setup (part 2)

Thinkpad T23 Setup (part 3)
http://www.freebsd.org/cgi/getmsg.cgi?fetch=154009+159374+/usr/local/www/db/text/2002/freebsd-mobile/20020519.freebsd-mobile

There is a more up to date patch that Orion did up a while back that 
apparently still hasn't been MFC'd for ac97.c.  The patch described in the 
part 1 of my post does work, and it's a far simpler tweak.

The good news here is that it looks like the 2 pr's that were referenced in my 
post have beem MFC'd, and should be available for you to use by doing a make 
world on a recent cvsup of STABLE.

Have fun with it!  These here Thinkpads are pretty nice boxes once ya get 'em 
all tweaked into play.
