Thanks to those who responded to my earlier questions about the "blank screen"
problem with NetBSD 1.1 and the Picasso-II. Since then, I have been digging 
into the nitty-gritty of Cirrus register access and have produced a modified 
kernel driver which has been running for the last few days on my A3000T. I 
now get the startup console and have been happily running X-Windows using 
the Xcl server.

The fix involves changes to grf_cl.c, ite_cl.c and grf_clreg.h so you will
need a working system with the kernel sources in order to be able to apply
the changes. (Picasso owners would have to either temporarily remove their card
or, as I did, initially recompile the 1.1 kernel on a 1.0 system)

If I don't encounter any adverse side effects in the next couple of days, 
I would like to make the changes available for anyone else who has the problem. 
I was thinking of producing a set of diffs and a readme and uploading them to 
ftp.uni-regensburg. Is this the best way to distribute this type of patch?
