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 ;)

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. 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.

have fun
