Much nicer. I'm glad I'm not the only one that hated the default WSCONS 
font choice for acorn32.

I did try X but I got an unable to initialise framebuffer error. I 
wouldn't worry about that too much as I couldn't even guarantee that X 
was working with the last kernel I used.

Working nicely here on a 1024x768 8bpp SA RiscPC (also with 2MB VRAM).

I found the following. When running at 1024x768 I was able to scrollback 
  more lines than were available in the text buffer but I'm not sure if 
thats a general wscons scrollback feature or not.

I also see console beeps causing occasional glitching of the screen. 
However thats minor compared to the aurateconv error that used to be 
there. I never could figure out what caused that bug. :)

Thanks for doing all this. Actually makes the console on acorn32 a 
pretty nice environment.
