The nice thing about GGI's abstraction is it allows binary-only drivers
(aka Permedia support) and other privately-developed drivers to be
incorporated simply...

Now things are still changing (a lot slower than last year but...) but the
scheme is designed so that _NO_ video driver code will be required in the

Unlike any of linux-kernel it is (will be for the most part) possible to
compile a videodriver in a seperate source tree. Or even just install
binary drivers for those companies too stuborn to provide public info (or
unaware that the GGI Media/GX support was written under NDA with Cyrix's
blessings and is nonetheless in source form).

Hope above comments help.

- My card locks my system when running SVGAlib or X.
(GGI fixes this... mostly. Gotta finish the drivers :)
[S3-ViRGE or S3-Trio64V+.. take yer pick]

- I run multiple videocards. fbcons does _NOT_ support multiple
PCI adapters. At least ones that don't initialize themselves.

- I've been pestering for kernel/userspace communications since
1.1.83-ish. EvStack is actually the first operational implementation
I've seen yet....

One last comment:
Anyone coding for libGGI is at an advantage on a KGI-supported
system. but their programs will run under X, text, terminfo, svgalib, or
other interfaces as well (without recompilation). The system may have a
lot of work to do but this library alone makes the project worth paying
attention to IMHO... (but it's a userspace issue and offtopic for
Linux-kernel, right?)

G'day, eh? :)
