Just had a go at reanimating DisplayServer on my empeg after upgrading to the 2.0 beta and found it is actually very easy! (well if you had installed DS on one of the music partions anyway). All I had to do was:
* mount the drives rw (& rwm of course)
* backup the old profile
* use zmodem to load the new profile into /etc
* correct desplayserver.conf and use zmodem to load it into /etc
(actually I created it from scratch - was easier :-) )
* create a symbolic link to the DS install location (/drive0/opt in my case).
* ro and rom everything and reboot
and since I wanted VolAdj back too ..
* flash mlords VolAdj kernel using Tonys kernel flash util in LogoEdit

See, piece of cake
