Last time I checked it, it was quite stable, although you probably
should give it some time yet unless there is a feature you really want.

test11 ran my dvd/cdrw using ide-scsi quite fine do I don't think
its broken (I don't believe it would live test<n> stage without
ide-scsi as its a widely used interface.
As for devfs it does seem that its been deprecated in favor of udev
(this is from test 11):

Note that devfs has been obsoleted by udev,
<http://www.kernel.org/pub/linux/utils/kernel/hotplug/>.
It has been stripped down to a bare minimum and is only provided for                                                    
legacy installations that use its naming scheme which is
unfortunately different from the names normal Linux installations
use.

Main things I saw that you would probably notice is that you need
module-init-tools since 2.4 modprobe doesn't work, different module
infrastructure. Also all mice are now repeated to /dev/input/mice,
including ps2 which is also repeated into /dev/psaux (I think you can
access them individually in /dev/input/mouse<n>
The make xconfig has also been changed quite a bit to use qt and there
is a new make gconfig for gtk.
On the surface, I believe most else will look the same (different
learning scheduler which should be somewhat faster and a preemptive
scheduler ...)
