Hello,

I just committed a generally overhauled tcx driver. So far it does:
- - work on my S24
- - supports wsdisplay with colour, virtual consoles, scrollback etc.
- - accelerates scrolling, character drawing and rectangle fills
It should work with any font up 
to 16 pixels wide ( I tested it with  FONT_GALLANT12x22 and FONT_BOLD8x16 ). Speed isn't all that impressive but still orders of magnitude better  than all software. But nobody would expect an S24 to break any speed  records anyway ;) This needs testing with 8bit TCXes. I tried to keep compatibility, the  driver should use only the 8 bit planes anyway but I have no way to  test it. Also, there is no support at all to run X yet. The code is still  littered with #ifdefs and comments that disable non-essential  features, stuff we don't need anymore etc., it's not as pretty as it  should be but it's good enough to be useful for now.

have fun
Michael
