I have a Full page MacAvenue card for my IIsi.  Every time I boot with it 
installed, I get a rather nasty kernel panic and it exits to the 
debugger.  I think it's coming up as grf1, but I have had it out for so 
long I don't remember.  Anyhow, I'd love to give the debugging info to 
someone so it could possibly ever be compatible.  Who on this list would 
be the applicable recipient of such info?
