Okay, I got some news to report - sadly, no success yet!
A tip from Aaron Grier led me to realize I could rule out (or in!) the
framebuffer as the culprit, by simply writing directly to it using
open(), lseek(), and write(). Doing so, I have been able to confirm
that the framebuffer appears to be working just fine. So I'm pretty
sure it ain't the hardware...
So I tried Ricardo's suggestion to use Microwindows CVS, which I did.
It took me a little while to sort things out, but I was able to try get
it compiled. I've been working with LTIB (the Freescale release from
last December, which has a newer kernel and supports 320x240 LCD).
Because I'm not sure how to add a new package to LTIB yet, I decided to
just apply the necessary patches (nothing too significant, it seems) and
I was able to build it in LTIB's "spoofed shell environment" - pretty
cool. But the results are no better than the 0.90 that came with LTIB.
In fact, the launcher.sh demo is significantly worse - the entire lower
half of the screen is all torn up, and there is significant flicker in
the upper half now too!
Now, I've learned a lot lately about Microwindows, LTIB, and the like,
but I don't have anything to show my client for all this effort. Worse,
I don't know what to try next. It just won't work for me! What am I
missing?
Attached is my latest config file for the CVS version - maybe someone
can point out something obvious?
Discouragingly yours,
-Bob

# Microwindows and Nano-X configuration file
#
# This package can be configured to run on Linux (MIPS, ARM, POWERPC or x86)
# UNIX, ELKS, DJGPP, or RTEMS.
# On Linux, we've got drivers for Linux 2.x framebuffers, X11, or,
# svgalib for VGA hardware.
# In addition, a gpm or direct serial mouse driver can be configured.
# On ELKS, the bios screen driver and serial mouse driver are always used.
#
# Either Microwindows and/or Nano-X can be built.
# Microwindows and Nano-X have several demos.
#
# For MSDOS makes, see mcmwin.mak and mcnanox.mak
