They made cards with the Rage LT? I thought that's a laptop thing.  
Yuck. Unfortunately I don't have one of those so I can't help but the  
LT is known to be problematic :/

That's a linux thing. The driver shouldn't need it, there should be  
an option to disable it - in other drivers it's optional and disabled  
by default, maybe it's just the other way around here.
Also, if I remember correctly we don't build the imstt driver because  
it's supposedly unstable, unfinished or something like that. And if  
memory serves it was a rather PC-specific thing with all the usual  
vgahw gunk attached so it's probably never been tested on a Mac.  
Shouldn't be too hard to clean up though.

good luck
Michael
