Hello Karesz and Mark,
I built the kernel 2.6.38.3 using Mark's config
Here's what it produces:
with KMS enabled
1) resumes from suspend OK
2) fb (framebuffer) is weird. The font looks nice and fine, however
no proper splash when booting
w3m-img displays blurry images in the console
3) it does not have 3d acceleration: no compiz, no stellarium is slow
"compiz --replace&" produces
compiz (core) - Fatal: Software rendering detected.
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0
Launching fallback window manager
Moreover,
The compiz-check program reports this:
Gathering information about your system...

There has been (at least) one error detected with your setup:
Error: Software Rasterizer in use
And, yes, this is what Mark was talking about :
glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Software Rasterizer
GL_NV_conditional_render, GL_NV_depth_clamp, GL_NV_fragment_program,
Apparently, the problem of non full direct rendering was discussed widely.
Possible solutions offered were tinkering the xorg.conf file, which I tried -
with no avail. So Rasterizing prevents it from full 3D.
I attach the difference between the configs (the graphics &frame buffer
sections), Mark's and generic. If the constants are identical, they are not
shown. Mark's config has no "extra" constants in these sections.
