Trying to build a driver for Imagine-128

[Tom May]

Hello all.  I'm stuck trying to build the driver for an Imagine-128.
Any help I could get getting unstuck would be great.  Or any help
getting the I-128 up.  Maybe I'm just an idiot.

My story: I tried firing up the X server for an Imagine-128 card using
the i128 driver on Ubuntu 5.10.  No luck.  I have not used this card
with Linux before so I can't say "it used to work".  Everything looks
ok in Xorg.0.log except at the end it says:

  Fatal server error:
  AddScreen/ScreenInit failed for driver 0

Not the most useful error message!  I'm just trying to run 1024x768x16
which is well within the card's capacity.  FWIW it's got a 3025 DAC
and 4MB VRAM (wow).

So I thought I'd build the server and driver myself and see what was
going on, since I used to do X servers as part of my job about 15
years ago, back before X386/xfree86/xorg, when all we had was
Godzilla's Guide to Porting the X Server.

Also five or six years ago I built a xfree86 driver for my laptop from
cvs while helping out the fine folks working on the Trident support
and it was really easy.

But building the latest driver/server code from cvs is not easy.

I got the latest code from cvs, installed all the latest auto tools
and everything else I seemed to need, ran:

CFLAGS="-O0 -g3 -pipe" util/modular/build.sh -n -d ~/xorg

and after a few rounds of installing more packages, and starting over
from a clean slate several times, I ended up stuck at the following
errors:

sed '/^#/ s|y\.tab\.c|gram.c|' y.tab.c >gram.ct && mv gram.ct gram.c
rm -f y.tab.c
:   lex.l
sed '/^#/ s|\.c|lex.c|' .c >lex.c
sed: can't read .c: No such file or directory
make[2]: *** [lex.c] Error 2
make[2]: Leaving directory `/x/src/app/twm/src'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/x/src/app/twm'
make: *** [all] Error 2
***** make failed on app/twm

Ok, I can live without twm, but I get a few more errors here and
there, and here are the ones I'm actually concerned about, first
building the main server(?):
