Erik,

Once I installed 1.3 from scratch I was no longer able to get any grf 
devices to show up at boot time on my 17" Nokia monitor.  All worked well 
on my 14" Apple Monitor though.  So, follwing the advice posted on the 
list, I made the mod to grf_iv.c and manually typed in the madhatter 
patch and magically I was finally able to run X in 800x600 (the most I 
can support).  I am really not sure what the problem was, but I was sent 
the following to fix it.

>>In grf_iv.c there is a line of code like:
>>	sense = (bus_space_read....
>>
>>	if(sense == 0)
>>	  found == 0 ;

WHen I commented these out and recompiled I got an error and my kernel 
didn't compile, so I went back in to grf_iv.c and a few lines above that 
there is another instance of the word sense, I deleted it and recompiled 
and it started working.  I should note that I also had applied the 
madhatter patch to machdep.c and then all went well.
