BTX problems are no fun, but they will need to be fixed on the FreeBSD side.

If you don't mind:

Grab a FreeBSD 7 ISO, and confirm the bug is there as well:


If the bug still exists, can you report it to the FreeBSD team? Be sure 
to include as much HW info as you can, and hopefully they can get it 
fixed here asap.
