I have a Quadra 950 (in addition to the Q650 which I've been using so  
far).  I'll set it up and check at some point if someone doesn't beat  
me to it.

If anybody wants to take Genie/Lamp for a spin, you can get it here:

Lamp Ain't Mac POSIX
http://www.metamage.com/lamp/

Once running, /sys/mac/xpram is a read-only virtual file  
corresponding to the 256-byte XPRam.  You can either hack it with  
perl or cat the whole thing into a real file and view it with HexEdit.

Also, the 'drvr' script will iterate through /sys/mac/unit and list  
all the installed drivers.

Bear in mind that at present I am Lamp's only user, so some gotchas  
are to be expected.
