Roughly the same story for me. My Inspiron 7500 is equipped with a 1280x1024 LCD
panel. It worked out of the box, modulo slight problems, with the XFree86 4.0.1
server. I didn't try XFree86 3.x because many people reported it wouldn't work out
of the box.
Here are the problems with X11:
1. If you suspend while X11 is displaying on the screen, the system may freeze.
Better switch to a text console before suspending.
2. Sometimes, after switching to a text console and back to X11 again, the mouse
may be frozen. Usually killing the X server (clt-alt-bksp) and restarting it
(I use xdm which restarts the server automatically) fixes it.
Note that you have to build XFree86-4 from the ports collection, it is not
available as a package due to security concerns in the Xserver.
If you suspend, then dock the laptop, and then turn it back on, it will lock up. I
am not sure if this could be fixed at all without major work, because docking will
bring an ethernet interface into the machine, which was not probed at boot time.
I also have sound working, without recording, after applying the patches described
in a recent message on this list (see below). This is all with FreeBSD 4.1-R.
Regards,
Georg.

Upon suggestion by Sean O'Connell triggered by a Maestro thread on -stable
I've tried the (beta) newpcm driver from
http://access.cent.saitama-u.ac.jp/~taku/freebsd/maestro/
It didn't compile on my 4.1-RELEASE box because of changes in
/sys/dev/sound/pcm/datatypes.h but following patch fixes that. I'm
not sure if it could be done easier, but this works.
Note that you have to crank the volume up quite a bit compared to the
OSS driver I used. Futhermore, there is no recording support (yet).
