 Is there anyone else having this problem? I'm running on IBM X30 ThinkPad.

   You might try changing the VT prior to suspending if you are not
   already.

Tried, but still doesn't work.

I looked into why 4_3_99_9 works, and anything after doesn't, and realized
that this portion of the code causes the problem.

It seems that loading the DRI causes the screen to go blank after resume.
If I don't suspend/resume, screen works fine.

Next, I tried disabling DRI ...

Option  DRI   off

and that fixes the problem. Screen restores correctly after resume.

I don't know how to fix the DRI to get it to restore the screen after
resume, but if someone is willing to provide guidance, I'll be more than
willing to help.

Thanks,
Jeff.

Unfortunately, there is no real dri support for suspend/resume.  The
only driver with support is the radeon driver.  you also need to have
suspend/resume support in the agp chipset driver.  See this apge for
more info:
http://cpbotha.net/dri_resume.html

Feel free to implement support.
