I am the maintainer of the tdfx(4) driver.
Table of GIANT-locked network drivers (where I found IFF_NEEDSGIANT flags): NetworkNeedsGiant
Additionally, I remain pretty active in the using-FreeBSD-as-your-desktop scene, and maintain some helpful work on keeping up with amd64 compatibility.

My own git repository: http://www.cokane.org/cgi-bin/gitweb.cgi
As part of the above work, I've been maintaining some patches to FreeBSD to fix some bugginess in the HP Compaq 6715b Notebook computer. I have some custom-rolled 7.0-RELEASE ISOs available here: http://people.freebsd.org/~cokane/iso-images/, as the default ISO kernel will not recognize the SATA HD on boot. You'll need to read the instructions on my page, however.
