Java is acting weird under the voodoo kernel 1.0

[othmam]

Hi again,

I installed different Leopard distros (iDeneb, XxX, iPC) and when I use the voodoo kernel java doesn't let me type or edit what I typed, it doesn't dispay a software correctly, it's all white, but when I use for example the ToH 9.2.0 speedstep or sleep then java works normally.

What do you think the problem comes from?
