[Cooker] video problems Xfree 4.0.3??

[michael]

I can't use my x for very much or it freezes giving me all kinds of 
technicolor static around my edges, and rendering all open windows 
transparent. Only sol'n is reset switch.

I have a voodoo3 2000 AGP and have experienced this in all xfree's except for 
3.3.6. Except briefly earlier in the week with a different kernel....

How do I switch back from 4.0.3 to 3.3.6 or is this some thing that can be 
fixed?
