Solaris Render and 32-bit pixmaps?

[Greg Hudson <ghudson MIT EDU>]

I've built GNOME 2.2 from source on Solaris 9, and have found that
programs won't generally run on my test machine; they get "BadValue" X
errors trying to create 32-bit pixmaps.

I believe that is because the machine has a somewhat lame frame buffer
("ATI PGX PCI 8-bit [m64]") which only supports a bit depth of 24.
Based on the discussion in
<http://bugzilla.gnome.org/show_bug.cgi?id=88662>, it would appear
that the X server is violating the spec by claiming to support the
Render extension without supporting 32-bit pixmaps.

Have other people run into this problem?  Are there known workarounds
other than rebuilding without Xrender?  (That's next on my list to
try; I hope I can build it that way successfully and that performance
is acceptable.)

Thanks.
