Hey guys thought I'd just post up.

I've got my Compal JHL90 running 10.6.4 very well with sound, graphics, and full openGL. Minus wifi and sleep.

I installed iATKOS S3 Revision 2 with the following options:
  • Voodoo HDA
  • Apple PS2
  • Voodoo Battery
  • Natit

I was then able to run all the updates and get it to 10.6.4 no problem.
