wscons, finally

[Michael <macallan%netbsd.org@localhost>]

Hello,

Now that Julian added wsdisplay support for bw2 and cg3 it might be  
time to finally switch NetBSD/sparc to wscons. Support for it has been  
in the tree for ages but the switch hasn't been made for lack of a few  
framebuffer drivers.
wsdisplay drivers we have right now:
- bw2
- cg3
- cg6
- pnozz ( for SPARCbooks )
- ag10e ( For Fujitsu AG-10e )
- cg14
- ffb/afb/various PCI boards on sparc64
We have X support ( accelerated when possible ) for all of them.

Notable omissions are ZX/Leo and S24/TCX, I might have an S24 in the  
near future and I think I have enough information to write both  
accelerated console and Xorg drivers.

What we'd gain from wscons:
- colour when the hw supports it
- acceleration with cg6, ag10e and pnozz
- more modern Xserver support ( native Xorg works but not all drivers  
have been ported, in tree XFree86 works )
- virtual consoles

So, are there any objections to switching GENERIC to wscons and  
leaving a warning about the unsuported graphics chips? They don't seem  
to be all that common anyway.
Also, genfb at sbus should work on Leo, with some fiddling it should  
work on tcx/s24 as well ( all it needs here is attachment glue for AFX  
instead of SBus )

have fun
Michael
