In 6pack driver here in linux,there's still 0.3.0 version,and if I remember
the end of 90' ,there was something 0.4.2 version for dos/windows.
It never came into kernel tree...

This morning I compiled kernel without APM and it has been running
from since.
Hope,that get it running more stable..9 hours max uptime was quite
annoying.

Ofcourse possibilities to start use mkiss......Hope someone should
find intress to look code and make improvements..My knowledge
is below zero...;-)

Still have to remember,that this is a hobby..isn't it?
