* chipsfb is flickering after exiting X.org
chipsfb has no modesetting support at all and the XFree86/Xorg chips

were apparently written for PCs running VGA text mode and rely on the
vgahw module to take care of restoring text mode - not what we need
most non-PC hardware )
That's what I thought. Not chipsfb is broken (maybe not complete), but
Xorg is. At least a bit.
It's kind of shared broken- and incompleteness ;)
When I got my 3400c I just wanted a not so terribly slow console so I
wrote chipsfb and left it where it is now - any non-accelerated driver
will have the same problem so that's not even a regression :/
Also, back then I had no sane way to hook up a CRT to a 65550 so all
mode setting I could test would be specific to panel output ( now I
have a revision 4 shark with the same graphics chip but I'd have to
add support for the VLB version which is slightly different and needs
the PCI code split out ) and I still couldn't test DSTN support which
needs some more special handling.
It's not like I'm going to run out of work any time soon ;)
If you feel like hacking chipsfb I have the official docs and they're
probably still available from Intel.
I'd like to, but I have absolutely no experience coding C or even
drivers. I know a bit of perl, shell and awk, and thats about it.
Any pointers to documentation where to start?
The manual is here: http://www.datasheetarchive.com/pdf-datasheets/Datasheets-14/DSA-279208.pdf
( couldn't find it on intel's website anymore )
* No working german keymap for X11, I'm missing square brackets, the
tilde and an @ the most.
No clue, my 3400c has a US keyboard.
Is there any way to use the wsconsole keyboard map in Xorg?
No. Keyboard handling in X is quite insane - it translates native
scancodes ( like ADB in your case ) into something resembling AT
scancodes which are then fed to XKB for further processing - it
doesn't know or care about wscons keymaps at all.
So, the least annoying way would probably be some xmodmap hackery.
