Me too. I went further, in that I modified the pixmap formats and
DepthRec's for the screen. All combos refused to work (i.e. fscked up
output or coredump). According to the DDX Porting Layer document, it
should have worked. A possible solution is to modify cfbmskbits.h but that'd 
mess up things for other depths (unless you cloned the Imakefile in cfb24
- hmm).

Hah. I just arrived in .uk; aside from the machines at work (most of which
run NT/SCO/Linux) I've got nothing to work on. For instance, my own
personal machine runs NT workstation :(. I've got a NetBSD/i386 box at
'home' but that's no good.

I think you just answered your own question.

I changed this locally but it didn't help. Neither did anything else I
tried, and I put about ~4 hours into this.

This is depressing. *sigh*.
